Is it possible to export the output expressions from Mathematica computations (e.g., equations) in valid MATLAB syntax?

4$\begingroup$ Which equations? Can you be more specific on what precisely it is you want to do? one equation? a list of them? Cut and paste? Programmatically export? $\endgroup$ – acl Nov 2 '12 at 22:23

$\begingroup$ @acl just an equation with Log s exponentials error functions. For example f[x_]=Log[...]+err[..]*Exp[..]. Something that sort. I know there is a command // InputForm but the output has for example $E$ which MATLAB will not understand. I only want to copy paste the equation to MATLAB. Still unclear? $\endgroup$ – Seyhmus Güngören Nov 2 '12 at 23:29

$\begingroup$ This is not exactly an answer, but do to the large chat under previous answer I would like to point out that ToMatlab, provides the page where you can find the package, however many struggles with not being able to download it. I had the same problem until I pressed down alt key and pressed the link at the bottom of the page. Might save a bit of time! $\endgroup$ – ALEXANDER Apr 9 '14 at 10:08

There is the ToMatlab package that will convert Mathematica expressions to MATLAB equivalents. For example:
<<ToMatlab`
Expand[(x + Log@y)^5] // ToMatlab
(* x.^5+5.*x.^4.*log(y)+10.*x.^3.*log(y).^2+10.*x.^2.*log(y).^3+5.* ...
x.*log(y).^4+log(y).^5; *)
It even conveniently breaks it using ... and can also convert matrices:
RandomInteger[5, {5, 5}] // ToMatlab
(* [5,0,5,3,4;
5,5,3,0,2;
1,4,4,4,4;
0,3,2,5,5;
4,5,5,1,1]; *)
However, it won't convert general definitions or things that don't make sense in MATLAB, such as patterns.
To install the package, extract the ToMatlab.m file to
FileNameJoin[{$UserBaseDirectory, "Applications"}]

1$\begingroup$ sorry but how can I use this package? $\endgroup$ – Seyhmus Güngören Nov 3 '12 at 0:28

$\begingroup$ You extract the
ToMatlab.mfile to$UserBaseDirectory/Applications/$\endgroup$ – rm -rf♦ Nov 3 '12 at 0:41 -
1$\begingroup$ @TMH When you download the
ToMatlabpackage from the linked site, you get a zip file. Unzip that file and copy theToMatlab.mfile to the location I mentioned. Replace$UserBaseDirectorywith whatever is shown when you evaluate that in Mathematica. $\endgroup$ – rm -rf♦ Mar 30 '13 at 18:25 -
2$\begingroup$ Can you in simple steps numerate what we should do and where? Like: 1. Write this code in mathematica! 2. Write this code in Terminal (mac) or similar. 3. Copy this file to that folder!. What do you mean with extracting something to something? I downloaded ToMatlab.m file, what does it mean to extract it? What software to use when extracting it? Thanks for your patience. $\endgroup$ – Your Majesty Jun 8 '15 at 15:22
