[Walter Roberson]

The way to see the code for the built-in functions is to get a job with MathWorks. And no, that is not a joke. The built-in functions are not available to users.

Answer 2

[TAB]

You can only see the source of matlab functions which are implemented a program files. Most of the matlab functions are precompiled and we can see source of such functions. Although a m-file exists for such pre-compiled functions also, but it contains only comments for help.

To explore the .m file of matlab function, use

>> edit <Function Name>

For example

>> edit fft
>> edit sin
>> edit repmat
