5 Controlling Code Generation

5-22

The Compiler processes the string arguments passed to the main() function

and sends them into the compiled M-function as strings.

For example, consider this M-file,

sample.m.

function y = sample( varargin )

varargin{:}

y = 0;

You can compile sample.m into a POSIX main application. If you call sample

from MATLAB, you get

sample hello world

ans =

hello

ans =

world

ans =

0

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 M ATLAB 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. When you compile a function into a POSIX main

application, the first return value from the function is coerced to a scalar and

is returned to the POSIX shell.
