Interfacing M-Code to C/C++ Code

5-49

callback that references the specified function. Without this pragma, the -h

option will not be able to locate and compile all M-files used in your application.

If you are using the

%#function pragma to define functions that are not

available in M-code, you must write a dummy M-function that identifies the

number of input and output parameters to the M-file function with the same

name used on the

%#function line. For example:

%#function myfunctionwritteninc

This implies that myfunctionwritteninc is an M-function that will be called

using

feval. The Compiler will look up this function to determine the correct

number of input and output variables.

Compiling MEX-Files

If the Compiler finds both a function M-file and a .mex file in the same

directory, it will assume that the

.mex file is the compiled version of the M-file.

In those cases, if the M-file version is not desired, use the

%#mex pragma to force

the Compiler to use the MEX-file. For example:

function y = gamma(x)

%#mex

error('gamma MEX-file is missing');
