Examples Overview

The examples in this section illustrate how to mix M-files and C o r C++

source code files:

• The first example is a simple application that mixes M-files and C code.

• The second example illustrates how to write C code that calls a compiled

M-file.

more function M-files and to code other parts directly in C or C++. To write a

standalone application this way, you must know how to do the following:

• Call the external C or C++ functions generated by MATLAB Com pile r.

• Handle the results these C or C++ functions return.

Note If you include compiled M-code into a larger application, you

must produce a library wrapper file even if you do not actually create a

separate library. For m ore information on creating libraries, see Chapter 7,

“Libraries”.

Simple Example

This example involves mixing M -files and C code. Consider a

simple application whose source code consists of

mrank.m, mrankp.c,

main_for_lib.c,andmain_for_lib.h.
