I got the answer with the help from someone. I put it here for others' reference.

// Output the results
plhs[0] = mxCreateNumericMatrix(col_outputBuff, row_outputBuff, mxINT32_CLASS, mxREAL);
int* outputMatrix = (int *)mxGetData(plhs[0]);

// Read in the data
for (int col=0; col < col_outputBuff; col++) {
for (int row=0; row < row_outputBuff; row++) {
outputMatrix[row + col*row_outputBuff] = outputBuff[col][row];
}
}
