Using Wrapper Files

y=0;

You can compile sa mple.m in to a POSIX main applica t io n . If y o u call sample

from MATLAB, you get

sample hello world

ans =

hello

ans =

world

ans =

If you compile sample.m and call it from the DOS shell, you get

C:\> sample hello world

ans =

hello

ans =

world

C:\>

The difference between the MATLAB and DOS/UNIX environments is the

handling of the return value. In MATLAB, the return value is handled by

printing its value; in the DOS/UNIX shell, the return value is handled as

the return status code. Wh en you c ompile a function into a POSIX main

application, the return status is set to 0 if the compiled M -file is executed

without errors and is nonzero if there are errors.

C Library Wrapper

The -l option, or its equivalent -W lib:libname, produces a C library

wrapper file. This option produces a shared library from an arbitrary set of

M-files. The generate d header file co ntains a C function declaratio n for each
