Hello Andrey,

Here is a simple example to show how multiline (programming) function, snippets and Area regions have given quite a significant improvement to SMath.

I just used your Runge-Kutta fifth order example and made a multiline function. Then I make a file and snippet from it
Here it is RKadapt.sm. I used the snippet and, just for testing, make two callings of the function (different precission) - here is the picture:

Then, I made a function and snippet for plotting points - here it is plot.sm
Here is the picture:


The final file I was playing with is here RungeKutta5-1.sm

This is great!!!Good Biggrinancing:

Regards,
Radovan

P.S. When making snippets for the portable version, the snippets are lost from the snippets manager after restarting SMath. I did not figure out how to keep them there.

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 Good
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" Biggrin

SMath Studio version 0.89 release 8 came out just in time when I needed to do some programming for solving multiple non-linear equations. Great Job, Andrey!

By the way, I posted a couple of tutorials for version 0.89 release 8, one on graphics, and one on programming. They're available at:

http://smath.info/wiki/Tutorials.ashx?NoRedirect=1

Greetings, and thanks again,

SMath Studio is a freeware but not an open source project. You need to run .exe file using mono to use it on Linux.

- If you want to install the program to your system you need to download and run SMathStudioDesktop.0_89_8.Setup.msi file (maybe it will be required to install .Net Framework 2.0 or above from Microsoft's web-site first).
- If you want to copy the program to your flash drive or don't want to install .Net Framework 2.0 (or above) then you can choose SMathStudioDesktop.0_89_8.Portable.exe.

Anyway, functionality of both this versions is absolutely the same.

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!

which version of moo is required for Linux. I'm confused.
I have Mandriva 2010.0 64bit and Mandriva 2010.1 32bit, both use mono version 2.6.4, however, the Mandriva 64bit version runs, but the 32bit version doesn't.
Any clues?

I also love this software, but slightly concerned with a lack of any newer versions being posted. Why not turn this into an open source project?

Any idea on when a new release might be posted?

I think SMath Studio does everything I need except for polar plots and log scale support - do you know if one or both of these features might be included in next update?

If those two features show up, I think all my MathCad files can be implemented in SMath which would be great for sharing.

By the way, I like SMath unit support much better than MathCad - it's much more obvious that a unit is a "unit" and not a symbol.

SMath could use a "ceil" and "floor" function as well.

Thanks much,
Doug
