Is it possible to export the equations from Mathematica to MATLAB?

Question

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

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?
@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?

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.

You extract the ToMatlab.m file to $UserBaseDirectory/Applications/
@SeyhmusGüngören could you please tell me how did you do that? I didn't get what rm-rf says with extracing ToMatlab.m file to...?
