A symbolic toolbox that provides MATLAB users with all of the symbolic and highprecision numeric capabilities of Mathematica. It uses the MathLink communication standard supplied with Mathematica and the MEX facility of MATLAB. In addition, since MathLink can pass native MATLAB matrices (and not just strings) between Mathematica and MATLAB, it is quick and easy to construct matrices in either system and pass them to the other. One can freely mix Mathematica code and MATLAB code without the bother of writing Mfiles to convert matrices into strings and back. The Mathematica Symbolic Toolbox for MATLAB is implemented as a single MEXfile and the source code is included. Precompiled linux and windows executables are included. Installation instructions for MACs are included in the README.Version 2.0 has been updated from:http://library.wolfram.com/infocenter/MathSource/624 to work with MATLAB R2007b and Mathematica 6.0.

Hi. I noticed some of us have problems with the following error:
"Error using mex
<commandline>:0:0: warning: "__STDC__" redefined [...]
<builtin>: note: this is the location of the previous definition
In file included from C:\Matlink\math.c:36:0:
C:\Matlink/mathlink.h:641:9: error: unknown type name '__int64'

What I did is add "#include <basetsd.h>" to mathlink.h header file, as _int64 is not recognized in gcc (MinGW 64 compiler) but in Visual Studio.

Hi, is there any documentation of the commands that are possible to use? How can pass a symbolic matrix from matlab to mathematica?

IInstallation steps:
1. Install the “MATLAB Support for MinGWw64 C/C++ Compiler” toolbox with Addons;
2. Copy mathlink.h and ml64i3m.lib from “C:\Program Files\Wolfram Research\Mathematica\12.0\SystemFiles\Links\MathLink\DeveloperKit\Windowsx8664\CompilerAdditions” to “D:\matlink”; (Note: “matlink” is just a name. You can name whatever you like.)
3. Copy ml64i3.dll from “C:\Program Files\Wolfram Research\Mathematica\12.0\SystemFiles\Libraries\Windowsx8664\” to “D:\matlink”;
4. Copy all files from “D:\Mydocs\MATLAB\AddOns\Functions\Mathematica Symbolic Toolbox for MATLABVersion 2.0\mathematica_for_matlab\math_windows” to “D:\matlink”;
5. Modify mathrun.m in “D:\matlink” as following:
a) addpath D:\matlink;
b) mlpath='D:\matlink '
c) mllib='D:\matlink\ml64i3m.lib'
6. Make “D:\matlink” as current folder in MATLAB, and run mathrun.m in the MATLAB command window.
7. Run testscript.m in the MATLAB command window. Choose math.exe in “C:\Program Files\Wolfram Research\Mathematica\12.0” if a dialog box with the title “Choose a MathLink program to launch” pops up.

I've managed to install this toolbox both on Win7 and Ubuntu 18.04 LTS, for Mathematica 11.2 and MATLAB R2017b. Thanks Ben Barrowers, it works very well on Win7. But I found a problem on my Ubuntu, i.e. , the process "WolframKernel" launched by math('$Version') (or any other commands) would not be killed by the command math('quit'), and was just left there in my system managers with the "Memory" colum showing "N/A". Further, if I run the two commands for several times, there would be multiple nonkilled "WolframKernel" processes. Anyone can tell me How I can solve this problem? Thank you very much!

I have found the solution for the issues that both me and "varan gupta" were having:
Make sure to include the module "ml64i3.dll" next to the compiled "math.mexw64" file, I found the module at:
"C:\Program Files\Wolfram Research\Mathematica\10.4\SystemFiles\Links\MathLink\DeveloperKit\Windowsx8664\SystemAdditions"
I just searched "ml64i3.dll" in the mathematica program directory to find the little sucker.
as long as the "math.mexw64" and "ml64i3.dll" files are in a directory within Matlab's search path you are good to go!

I am using Windows 7, MatlabR2015b, Mathematica 10.4 and having the same issue as "varan gupta".
Attempted to use Visual Studio Express 2013 without much luck on "mex setup" to recognize it. Finally switched to "Visual Studio 2012 Pro which is free online and got the sucker to compile using the "ml4i3m.lib" as mentioned before.
Any luck anyone?

Justine (view profile)
Firstly, thank you this is extremely helpful!
However, it took me 3 days to get this to work, so I thought I'd share what worked for me (Mathematica 10.0, Matlab R2014b, Ubuntu 14.04):
When setting up mex, make sure to change all instances of 'gcc' to 'gcc4.7' and change 'g++' to 'g++4.7' in mexopts.sh
include_path = library_path = /usr/local/Wolfram/Mathematica/10.0/SystemFiles/Links/MathLink/DeveloperKit/Linuxx8664/CompilerAdditions/
The readme file's "libML.a" is "libML64i3.a" for me, so I needed to type:
mex Iinclude_path Llibrary_path lML64i3 math.c
For point 3), I just added the whole folder by adding the following to my startup.m file (not sure how bad that is):
addpath(genpath('/usr/local/Wolfram/Mathematica/10.0/Executables/'));
Even after exporting the LD_LIBRARY_PATH the shared libraries were not being found. After much time spent with nothing helping, doing the following worked:
create a file in /etc/ld.so.conf.d called, say, mathematica.conf containing library_path, i.e. for me the line:
/usr/local/Wolfram/Mathematica10.0/SystemFiles/Links/MathLink/DeveloperKit/Linuxx8664/CompilerAdditions
save the file and then type:
/sbin/ldconfig
If you then type the command:
/sbin/ldconfig p  grep libML64i3.so
its presence should be shown along with the path to it
I hope that saves someone some of the time I lost!

Successfully compiled under Windows7 x8664 with MATLAB R2014b and Mathematica 10.0.0.0 using the default math.c (not the one from 'math_windows.zip') and ml64i3m.lib instead of ml32i1m.lib.

The compiled file 'math.mexw64' seems to work mostly fine on my machine (quick test with the examples from the README  only thing that didn't work was the command 'diag(hilbert)')

I've used this for a few years and find it works very well. I'm trying now to compile it on a Mac running OS 10.7.5
I'm using the command
mex I/usr/include/ lMLi3 math.c
and get
if: Expression Syntax.
ld: library not found for lMLi3
collect2: ld returned 1 exit status
mex: link of ' "math.mexmaci64"' failed.
The library file is definitely in the directory I'm specifying. I see a note in the README that the library path needs to be on the (DY)LD_LIBRARY_PATH  could this be the problem? Any advice would be appreciated

This works under x64 environment;

You have to use mldev64\include and lib\ml64i3m.lib instead of 32bits one.
Be careful not to use Visual Studio Express edition.
I failed to compile mex at first, as they have no x64 libs.
Thx.

As usual from this author, a great addition to MATLAB. Quick note for those compiling on OS X  make sure you edit math.c line 227 as suggested in the comments below it, but don't worry about setting the library path. Your mex line should be something like:
mex I/Applications/Mathematica.app/SystemFiles/Links/MathLink/DeveloperKit/CompilerAdditions/ L/Applications/Mathematica.app/SystemFiles/Links/MathLink/DeveloperKit/CompilerAdditions/ lMLi3 math.c

In case anyone gets here b/c they're having the same problem I was, I figured out how to fix the problem.
The issue is that when you do: lML the compiler looks for a library named libML.a. However, on my machine the library is named libMLi3.a.
Therefore if I run:
/Applications/MATLAB74/bin/mex I/Applications/Mathematica.app/SystemFiles/Links/MathLink/DeveloperKit/CompilerAdditions/ L/Applications/Mathematica.app/SystemFiles/Links/MathLink/DeveloperKit/CompilerAdditions/ lMLi3 math.c
Then everything works out hunky dory.
Thanks,

I can't get this to compile on my Mac (OS 10.5.5).

ld: library not found for lML

mex: link of 'math.mexmac' failed.

Anyone have any suggestions as to why that is not working?

dear ben do you know why i recieved incorrect result by this:
k=sym('k','positive');
z1=1.21+0.008*i
k1=((z1k))^(1/2);
t=2*pi*k/(imag(k1))
s=int(t,k);
Not thoroughly tested, but so far appears to do just what the help files say. This is an invaluable tool to supplement the numeric and applicationspecific capabilities of MATLAB with the symbolic and programming (Map[], Apply[], etc.)strengths of Mathematica. Just what I needed. Fantastic! (Note: MathSource link is not right as of 20060531. should be space between final '624/' and 'to'.)
Wow! Appreciate this a lot.
