Hello,

I try calculate the LambertW function as in the after-mentioned example. During calculations I receive the answer: "function is not defined". I found the name of LambertW function in the cmds file of MapleWrapper plug-in, but I'm not sure that the function is implemented in that plug-in. From the prompt of the plug-in or SMath Studio - I'm not sure, results that the function is not implemented in MapleWrapper. Please for the confirmation is that function implemented or not. Maybe I do something improperly?

_________________________________

Smath does not access Maple "Lambert W" and it is absent in Smath ... bad luck ? !

Not so badluck: I posted [about a month ago] the principal branch, the one that solves
all commonly Lambert W stuff. Where did I attach ? maybe in "Samples". If you can't find
please let me know.

OK, there Maple and Maple Smath.

Visit the Laplace DE solvers just posted in "Samples"

From the posted examples, what a piece of crap Maple in DE's
And you guys don't put the DE in formal "format", that is
most, most, important. That reminds me the Cadarache story.
Many Mathsoft Collabs broke their neck trying to solve DE
instead of simply integrating that peak surge .

Guess that the best alternative to maple V is xcas: https://www-fourier.ujf-...le.fr/~parisse/giac.html . It is very compatible with maple syntax. After install, check the files aide or aide_cas. There are nice functions like: maple2xcas, maple2mupad, maple_mode. Also, giac.exe can be called from cmd line as giac < infile.txt > outfile.txt, taking maple-like commands. Hope that with that, uni job translating maple to smath and viceversa, can be more or less eassy to this other cas.

Best regards.

Alvaro.

"uni job translating maple to smath and viceversa" is what uni do in the past, I'm not say anything about who can or must or someting else in the futur. That translation is done, and even my english is very limited, and must to search words like "polite" I don't see any un-polite point in my post. And I use "phrasing that would make it apparent" because, precisely, I don't give orders. After uni starts that project, some years ago I ask (and at this time I actually ask, as you say) for change from MapleV4 to MapleV5, just because this other version is more compatible for futur developments, even MapleV4 is the mathcad 11 version. For example: V4 uses `` as string separator, and V5 "", and have a lot of other oddities which make that version very impractical. Can check that reading old posts in this entry. Given that, and the problems about the licence of maple, issues with maxima plugin, and other considerations, I see a good time right now to point to an open source kernel with maple compatibility, and complete, in some sense, my old recomendation, saying that for me is the best option to maple, attending that what was developed can be re-used in a new plugin, hoping that this change from V4 to V5 can show now that was a good choice. Is that enough polite for you?

Alvaro.

Hi Uni,

Could you please look at cic3-1.sm (8kb) downloaded 93 time(s).what is wrong with Maple plugin in Smath 098.6060 ?
The attached worksheet works once after I delete all files in the plugin directory
\32dfd679-8cfd-483a-b79a-19d5ea838750\1.0.6003.18809\mvr5\tmp\*.*
Next time it fails with a message "Cannot create a file when that file already exists".
Smath 098.5973 is the last working fine with Maple Wrapper.

Best regards

Though I don't understand immediately the Maple coding,
must admit it enables plotting this non plottable function.
Does not plot either in Mathcad 11. I bet the coding originates
from some "Maple smart cat". Thanks => saved

Hello Uni,

Thank you for your efforts of supporting Maple plug-in.
But since Smath 5973, most of my worksheets failed to work.
The next bug, hopefully is that the later Smath
puts some "unwanted" placeholder for units into result of some symbolic calculations.
The attached screenshot shows such a problem.
If "t" was obtained as a result of calculation, the further symb. calculation failed,
but if I assign "t:=" by copy-pasting the value stripped of the placeholder, it works !
It also possible that some trailing character is removed from the result string.
Uni, could you please look into this issue ?

Thanks and best regards.

... your working 't(x)'should plot something, is it ?
Coefficients by themselves have strictly no meaning,
they DO IF you need the roots. Then your vector of
simplified coefficients will fail, why ?
Smath "polyroots(v)" is slightly underdesigned.
The terminating coefficient CAN'T be '0'.
So, it will report " result above max allowed... "

Cheers, Jean

Sorry for my Electronic Engineering background 60 years back.
"digital feedback loop filter" rings two bells.
1. LMS filter
2. As you have 4 coefficients, the matter may be Fourier,
pad up, pad down, pad center ... pad at will.

With so few information: can't help.
Mathcad 11 was pretty good at this stuff: Signal Processing Pack,
the DSP download from web ...

You can not install the Maple plugin in Smath Studio , if Smath Studio is in Spanish.

If you put Smath Studio in English , then you can load the plugin Mapler , but when you changes again Smath Studio to Spanish and restarted, then the plugin will not start.

Best Regards

Carlos
