9.3 TheMatlabengine functions 293

The following C++ code contained in the filemexec.ccasks forMat-
labcommands, which are then processed byMatlab. The result is put in a
memory buffer and displayed on the screen, and the session terminates when a
zero (0) is entered instead of a command:

#include <iostream>

#include "engine.h"

using namespace std;

int main()

{

//--- Start a matlab engine session:

Engine * skilaki;

skilaki = engOpen("matlab -nodesktop -nosplash");

//--- Define a character buffer:

const int BUFSIZE=256;

char buffer[BUFSIZE];

engOutputBuffer(skilaki, buffer, BUFSIZE);

/*--- Define a character array to host a matlab command:

Initialize the first character to 1 */

char matcom[50];

matcom[0]=1;

cout << "Please enter matlab commands: 0 to quit:"<< endl;

//--- Keep asking for commands until 0 is entered:

while(matcom[0]!= ’0’)

{

cin >> matcom;

//--- Transfer the command to the matlab workspace:

engEvalString(skilaki, matcom);

//--- Display the matlab response:

cout << buffer;

}

//--- End the session:

engClose(skilaki);

return 0;
