Hi,
I used the following code to open ML four times but it works fine:
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include "engine.h"
int main()
{
Engine *ep;
int retstatus,i;
char ch;
for(i=1;i<=4;i++){
ep = engOpenSingleUse(NULL,NULL,&retstatus);
if (retstatus != 0) {
fprintf(stderr, "\nCan't start MATLAB engine\n");
return EXIT_FAILURE;
}
if (engSetVisible(ep,1) != 0){
fprintf(stderr, "\nCan't make MATLAB engine visible\n");
return EXIT_FAILURE;
}
printf("Press any key to exit\n");
ch = getchar();
engClose(ep);
}
return EXIT_SUCCESS;
}
I can also open 4 MATLABs at the same time without any problem (tested in 12b 64bit Win 7).
Can you post a small reproduction code which raises the error you get?
