Very impressive changelog this time - waiting for a Linux version

Wow!! it's a big step for SMath. Congratulations

Hello Andrey,

I wanted just to remind or to point out on roots finding (solve, roots) once more. As we know the roots can not be found for the f(x)=0 if f(x) is numerically defined - actually if the functions returns only the numerical values (as well as if the function is defined with "if" ).
Here is the trivial example - by using eval:

I am very satisfied with SMath progress. We have "roots" function now, multiline function etc. and everything else introduced in this relese
However, I hope that sooner or later (not for this release) the feature of roots finding when numerical values are returned from the function will be introduced in SMath (although we can make those functions ourselves - f.e. Broyden's method on Wiki). Now when we can use multiline functions, and with "eval" we can drastically increase the speed of calculation, some robust roots finding algorithm for these cases incorporated into SMath would be very welcome.

Regards,
Radovan

P.S. Of course, it could be done quickly if there were few Andrey "clones"

Is there a PPC version too?

is the source code available. I would like to compile it under mono on mac.
how do you run this under Linux. I have Mono 2 installed on ubintu 10.10. is there a special way to execute in the included exe file

sir,
I see :
1)desktop windows :
smathstudio desktop 0 89 8 setup.exe
------- do --------- ortable.exe
desktop Linux
------ ---- I do not hace Linux , so I will not use this.

I have windows XP. I want to know which file / files I should download ?
thanks and regards

Hi there,
I just figured out that in the Linux version there is no possibility to change the font size (I think there has never been a possibility to do so).
Is this intended or are there any problems with this?

Many thanks for your great application!

Jakob

love this software, any idea when there might be a new build?

New build is in development stage now.
