Hello,
I have been using Mathcad since ever but my good old XP is quiting and I need a new life. I'am now under Ubuntu and I need to know if a ) Smath works under Ubuntu 16 and b ) Can I directly import Mathcad files and use them in Smath ?
If answer b is no I suppose I have to painfully re-write all my archives ? But that will be a lot of work !

Hello Mitcher3,

Welcome to SMath! There is a version of SMath for Linux, please see the download page.
About importing files from Mathcad: SMath can import .xmcd files, but my experience (but is from few years ago!) is that you will lose parts of your worksheet. I suggest you make print-outs or pdf's of all your mathcad sheets, so you can eventually rewrite the lost parts in SMath.

Regards, csb.

Thank you very much for your answer.
My files are in .mcd format (Mathcad 8) so I can try to import/convert, and if eventually some parts are lost or damaged I can try to repair or fill-in maybe, what do you think ?
I have seen that Smath is Linux compatible indeed, that's even why I started an interest in it but Ubuntu is not specifically mentionned. Any feedback on this ?
I think that if Smath has some view of competing with long-time heavyweigh Mathcad, these should be important features to bring forward. Mathcad is not Linux supported and it is a bad idea in regards of a lot of researchers and engineers and students using this OS.
Best regards

Hello Mitcher,

My files were also in .mcd format... I used a trial (30-day) license from Mathcad 15 to translate the files to .xmcd format (and created the .pdf of the files at the same time).

I have no experience with Smath on Linux at all, but you can search the forum for this subject.

Regards, csb.

_________________________________

Mathcad and Smath are two different animals. There are lot of similarities.
Not a single piece of Mathcad is convertible to Smath. You will have to
re-code all your *.mcd stuff. My last Mathcad was 11 + all extension packs.
On May 30 2015 the b......s PTC revoked their C-Dilla [Safecast] Microvision
protection. So, all Single User Editions got zapped using Mathcad 11.
Mathcad 8 was not protected and you can get a new XP computer and continue
using Mathcad 8 [do you have 8 Pro. ?]

I joined Smath Community 25 months ago and since work every day converting
my Mathcad stuff [a monk job]. Surprisingly, lot of Smath present better
than Mathcad. Smath is horribly slow in many tasks. Essentially, plotting
is much different but does very good job. Smath has an alternative to
Given/Find but does not have the gorgeous MCD "Minerr", though I have
coded the Conjugate Gradient Genfit, and when it works, works as fine as
MCD. Essentially also, Smath indexing is 1 thus rendering many MCD difficult
to convert. Essentially also, Smath does not allow to index the LHS argument
thus not rendering well Mandelbrot and few more.
Smath CreateMesh is much different than MCD but renders well the the u,v,z
vector functions. Smath does not have matrix 3D plot, thus eliminating
the Catmul-Clark 3D meshing. In replacement of the 3D gorgeous MCD plot
you may want to try "Dislin" or Scilab, both freeware. Since the spring,
2017, Scilab is no more available for XP.

All the good stuff I do from MCD to Smath is published in "Samples".
Actually, I work Smath on a small laptop because my XP Home Edition
defuntised itself November 2016. Most interesting, The Maple/Smath are
superb companions. All my Laplace/InverseLaplace work well.
Eventually, you can ask the forum about some MCD if it can be done Smath.
I have already > 900 Smath work sheets [~ 100 MB]... forget putting that
in the Forum. About ½ are MCD/Smath Engineering documents. I have no e-mail
working, no printer, but "Poste Canada" delivers anywhere in the world.
If you are interested: we can exchange our addresses and arrange for an USB
shipment of all my Smath stuff.

Are you a "Generalist", or in specific "Scientific/Engineering ?

Welcome to Smath Community. Jean

@csb531, thanks but from what you are saing seems hopeless, i will have to re-write it all.
Computer science is still in its infancy, looks great but when you scratch you find lots of problems and no format
or support is designed to last. It might become one of the biggest problem of this century.

@jean, I was using Mathcad as a tool to archive my own research in cosmology and others topics, some works of mine are 30+ pages long plus it's going to be a pain to learn how to use this new program. I believe Mathcad was the best tool ever designed for this, I have discovered they now commercialize Prime 4.00, supposed to be thei lattest version but unfortunately it does not work for Linux either. So short-sighted sometimes those companies...
How come you have no e-mail ? Or do you worry to send your work through the Web ? I would.

Yes, SMath Studio works even under ubuntu. Besides the official link, there is even a package made available by other users of the community here.

As stated above xmcd import plugin has some limits, because SMath is not a clone of mathcad, hence there are several differences that cannot be solved with automations, some because the core design, some because the philosophy (e.g. base-1 ranges instead of base-0), therefore his main goal is to import the most things as possible to make smoother the transition; however this plugin is an open project and everyone who finds some limits and think they can be fixed he can try to improve the plugin itself (sources in our SVN).

@Jean there are several ways to share files over the internet even without an e-mail address, f.e. uploading files in our wiki or using external temporary disposable services (f.e. volafile).

Oh ! Davide, I know better than that,
while my Mathcad 11 was still live, I maintained my huge web site
free from Google https working charmingly. I have an e-mail in my
laptop, but don't know where ... at least: I have gmail.

Thanks, cheers ... Jean

Hello Mitcher3,

I know nothing about "Cosmology" except for having done in Mathcad 11
Lagrange points, Kepler elliptical sweep segment, plot Analemma on sphere.
More maybe said: Smath Gamma(x) is only 4/5 decimals accuracy [ if you need
more => zap, no way vs Mathcad 15 decimals]. On the date [2006] PTC acquired
Mathcad from MathSoft, PTC lost the benefit of Maple symbolic. Instead, they
used MuPad that disappeared, then MCD 15 was symbolic Maxima.

PTC/Mathcad 14 could not read Mathcad 11 and could not backward save 11.
On that: there is a long dispute between Jean/PTC
What about MCD 15 and the "Primes"... You can try reading your MCD 8.

PTC is a "fishing organisation" ... fishing for Mathcad users clients.
Explain: when you downloaded Mathcad 15, it would install for 30 days.
Their download link was triple that the user does not see and unaware.
A triple link is a "malicious" [malicious to me because unaware of the
under the hood]. Their triple link attached in suite: Mathcad 15,
a spy software and the 30 days time stamp. The spy software was a link
to a web server in Costa Rica, several pages of sub links that would
read all your e-mails [obviously the clients ... and the visited web sites]

Please, don't hesitate to attach an *.PDF Mathcad 8 work sheet, or even
simpler: make an image of Mathcad using IrfanView.

Cheers, Jean

Wow Jean what you are saying is terribly awfull about PTC, really stupid of them, they had a terrific tool and they ruined it completely.
I found your post by pure chance by the way, I find this forum a little bit confused and unclear, don't even know where to attach files, but it looks powerfull with lots of functionalities..
Are you really saying SMath only works with 4 or 6 decimals ? It would be very poor when compared to the 15's Mathcad indeed.
Kepler is more astrophysics than cosmology but if it can do that it can do basically anything I guess.
From the name I imagine you are a french locutor, right ? (I'am).

Any Suggestion about forum organization is welcome, if you have some, we'll pass to the author Good
Also, if unsure, better to post a question in a new topic instead of using existing but not related. I've merged here some posts, since they are on topic with this thread.

About the attachments, there's a button in the post editor, click it, then choose "upload new file(s)" and finally when you're done "start upload(s)"

SMath has 15 digits precision on numerical calculations and full precision on symbolical calculations. Some functions are approximations though, those have less precision (f.e. Gamma function).

Regarding Mathcad and SMath one can see this on the SMath project site FAQ

Q: Why some of my Mathcad files cannot be opened in SMath Studio or can be opened only partially?
A: SMath Studio and Mathcad are two different applications which have their own unique features. There is no goal to support files of any separate applications in SMath Studio as there are too many incompatibilities between programs and it is actually too dangerous to perform such conversions automatically. Yes, SMath Studio has a built-in limited support for XMCD files, but it was developed just to simplify migration process for Mathcad users a bit. XMCD plug-in for SMath Studio is an open-source project, so anyone can do some improvements if required.

Thanks but it is the first time I hear about Mono (?) used instead of Linux !
If I understand right I have to download 2 Mono files first and THEN download SMath and it will automatically adjust to Linux ?

===========================================

Functions in computing machinery are all approximations from the basic 4 arithmetic operations
[+,-,*,/]. Many of them are built-in Microsoft [Trig, exp, ln, inverse Trig ...]. Those native functions, Smath probably borrow them directly, like others do. More of the Smath functions
come from other packages [Matlab ...]. Generally except for Gamma(x) numerical approximations
are code for 21 digits internal and carried as such between calculations. Cody Junior explains
that only 18 digits are true and that consequently to chained calculations, only 15 are displayed
and by same token meet reference tables [Abramowitz ,...].
Gamma(x) is the only exception I discovered recently while attempting to code the Barnes hyper.
BTW, Smath is a 32 bit CAS [Computer Algebra System]. Those CAS that display > 15 use an internal
"Big Number Engine" [Mathematica, Mathcad from symbolic]. The "Bible" of computer approximations
is "Hart et al", Luke is another source in Fortran.

On the first day you will post a problem in this forum, many will visit and help get started.
In Quebec we speak mostly 3 languages: French, English and "Quebecois" ... I speak the 3.

Cheers mon ami, Jean

PS: Not a joke, I heard about Smath from the PTC forum [Fred K.]
So many got pest off from PTC policies money makers ...
