Way to convert code into a mathematically readable format ...

Hi, a simple question but perhaps no easy answers:

Does anyone know whether there is an algorithm or way to convert code (e.g. java, c etc) into a mathematically readable text format. One example is:

Input:

A = ( ( ( ( ( (X ) * Y ) / Z) * Q) * P) / R );

Output:

        X * Y * Q * P
A = -----------------------
             Z * R


Thanks for any advice.

I don't know about the Matlab symbolic toolkit, but this is the kind of thing you can do in Mathematica and/or WolframAlpha if it's just a one-off:

In MATLAB? Take a look at the PUBLISH function or, if your expression uses
symbolic variables created using SYM or SYMS from Symbolic Math Toolbox take
a look at the PRETTY function.

In general? LaTeX, MathJax:

or some of the other options here:

Hi Steven,
Actually I was searching something more simple who can generate the equations in text format. Maybe the example was too easy, because in C codes there are lots of things which don't correspond to Matlab coding rules. I don't know whether the methods you told can handle them well.

Anyway, thanks

Hi Justin,

Thank you for the link. It works for my simple example, but if i put complicated c codes into the box, then it doesn't work. Maybe the strings from codes are too long for the processor
