Mixing M-Files and C or C++
• main_for_lib.c, which contains one main function
•
main_for_lib.h, which is the header for structures used in
main_for_lib.c and multargp.c
multarg.m
specifies two input parameters and returns two output parameters.
function [a,b] = multarg(x,y)
a=(x+y)*pi;
b = svd(svd(a));
The code in multarg p.c calls m lfMu ltarg and then displays the two values
that
mlfMultarg returns.
#include <stdio.h>
#include <string.h>
#include <math.h>
#include "libMultpkg.h "
/*
* Function prototype; MATLAB Compiler creates mlfMu ltar g
* from multarg.m

void PrintHandler( const char *text )
{
printf(text);
