Accessing code for built-in functions

Hi,

I cannot use the open or edit commands to see the source code for built-in functions. When I do it I can only see the comments that are included for that function but not the actual code.

I'm trying this on functions like plot.m and fft.m

I hope somenone can give me advice.

Best,

Taygun

What were you hoping to do with the source code for those built-in functions? If you were hoping to convert them to another language (specifically C or C++) some of them are supported by MATLAB Coder. fft is supported by MATLAB Coder, plot is not.

These functions are not accessible to users as they are MATLABs proprietary code. They are p-coded, which its matlabs way to obscure code. You can only see the header of p-coded files.

You may still place breakpoints and see what they do with the workspace, but you will not be able to see the source code.

[Walter Roberson]

more correctly, a lot of them are built-in functions coded in C or C++ with occasional Fortran as well.

Thanks for the answer Max.
