I would like to compile a P-file or a MATLAB file that calls a P-function.

This enhancement has been incorporated in Release 2009a (R2009a). For previous product releases, read below for any possible workarounds:

The ability to deploy P-code is available as of MATLAB Compiler 4.0 (R14). However, a P-code function cannot be compiled directly but must be wrapped by a MATLAB file. For example, if you create a function:

function ptest
disp('Hello from P-code');

and then use PCODE to generate ptest.p, you will not be able to successfully compile PTEST. However, you can compile code that calls this P-code, as in:

function pwrap
ptest

Note that compiling P-code will not enable the source code to be revealed since MATLAB Compiler 4.0 does not generate a C translation of the code.

If you are using a previous version of MATLAB Compiler, read the following:

The MATLAB Compiler can translate MATLAB code into C, C++, or P-code. The MATLAB Compiler does not compile P-code or MATLAB code that calls P-code functions.

There are no workarounds for compiling P-code. P-code can be used to hide algorithms and translating it is therefore not an option. For more detail on the differences between MATLAB code and P-code, see the Related Solution listed below.
