I agree. Maybe, just an adjustment of the command line for establishing the socket connection is required. Under Windows I use

maxima-installation-path/bin/maxima.bat -l sbcl -s <port number>

This requires
- the .net socket stuff and process control to work under mono,
- a unicode-proof lisp compiler to be installed (which accepts utf-8 socket encoding), under win the only one is steel bank common lisp (SBCL).

Also, I need to know the name of the maxima process for detection of active maxima processes via System.Diagnostics.Process.GetProcessesByName(name). This is required to identify the pid for later kill. Under windows this might be "maxima" or "lisp" or "sbcl". This has changed over the years and may be different under linux.

The plugin might work even as it is, if the maxima startup script is renamed to maxima.bat.

Any information from the linuxing SMatheers is welcome.

BTW, there is a maxima build for android as well...

EDIT: It would also help, if someone could explain me how to build and debug the plugin under Linux. Under Win, I use VS 2015 with the project as found in the SVN repository. Otherwise I need to blindly make changes under win and install and test under linux. This would be a huge drawback compared to the win-only workflow, where compiling and running SMath with the new build in the debugger is just a push of a single button...

I just did some tests on a linux mint 17.2 virtual box with smath 6654:

install maxima, copy /usr/bin/maxima to /usr/bin/maxima.bat

Insert> maxima> settings: Path to maxima: /usr/bin

Then smath crashes with the following console output. Understanding this is beyond my experience level in c#.

The path is a mix of windows and linux style: "/home/user/.config/SMath/extensions\plugins\44011c1e-5d0d-4533-8e68-e32b5badce41/maxima.xml" plugin should be use '/' instead '\'

Btw I suggest you to link maxima.bat to maxima instead of make a copy
Code:
sudo ln -s /usr/bin/maxima /usr/bin/maxima.bat



On linux an IDE similar to visual studio is "visual studio code" also by MS, you can use it with C# extension

Thanks for the comment. Seems that fixing the path separator might be a goot starting point. There must be something like SystemPathSeparator in C#, I shall find out...

Also, I shall get a more recent linux virtual box with enough space to install VS code.

If you public (is it already?) the code I can also give you an hand.

If you make a new virtual machine maybe is better that you use Ubuntu to develop that is ~more standard~

Third party SMath plugins are always open source. Here is the link for the Maxima plugin.

Feel free to play around with it. I guess one of the first steps will be to make the VS sln file fit for cross platform portability.
And we will need to set up a utf-8 maxima binary under linux. Under windows this is SBCL. It is available under linux as well but on my box this requires separate compilation.

BTW, Davide has offered help with streamlining the install procedure (automated maxima installation). I guess that the BTS issue SS-3562 is the right place for further discussion and co-ordination.

Ubuntu is fine for me.

Thank you Martin,

I tested it briefly with a larger data set and more than one dependent variable. At a first glance it seems that it works surprisingly fast. I might have forgotten but I think there is not yet a strictly numerical procedure in SMath (available via plugin) for nonlinear fitting a quite large data set to a function with multiple dependent variables.

Radovan

In the attached, the functional version of the Carlos' version of LM. For some large set of data, as Omorr ask, the main problem it's the Jacobian. There are some algorithms that don't use it. In this approach, actually it's a truly mix of numerical and symbolic manipulation for the Jacobian.

lmCarlos.sm (58kb) downloaded 51 time(s).

Best regards.
Alvaro.

The problem remained unsolved

However, it seems that Det(),Diff(),Int(),Lim(),Sum() are working well.

Int() certainly does not work.
Why bother Maxima, unless some like that cluster fuck

I confirm that the API issues seem to be resolved. Andrey, thank you very much, I might not have been able to fix that soon.

In the test suite (Plugin maxima test.sm in the interactive handbook) there is just a new issue with displaying svg images in the Maxima-Draw-Region and in the image region. PDF and PNG work fine though.

Best regards, Martin
