Your C code, in its present form, will not compile. I suspect that the executable you have is a stale result of compilation of an incomplete earlier version of the code. Nevertheless, here is how you can make this code working with minimal changes:
#include <stdio.h>
#include "codegen/exe/test3/test3.h"
#include "codegen/exe/test3/test3_emxAPI.h"
#include "codegen/exe/test3/test3_emxutil.h"
int main(int argc, char **argv)
{
/* Ansi C requires you to declare your variables
in the beginning of the function */
int size_array;
int index;
double *array_vals;
double result;
int i;
emxArray_real_T *input;
size_array = argc - 1;
/* You need to do a dynamic memory allocation here
because size_array is not a constant */
array_vals; = malloc(size_array * sizeof(double));
for(i = 1; i < argc; ++i ) {
index = i - 1;
array_vals[index] = atof(argv[i]);
}
/* Create the emxArray to pass to test3. See test3_emxAPI.h */
input = emxCreateWrapper_real_T(array_vals, 1, size_array);
/* Note the function signature of test3 in test3.h */
test3(input, &result);
printf("%f \n",result);
/* Free the dynamically allocated memory and emxArray */
emxFree_real_T(&input);
free(array_vals);
}
