How to iterate through a cvMat matrix in JavaCV?

Question

I have an IplImage that I converted in a Matrix, and now I want to iterate cell by cell.

CvMat mtx = new CvMat(iplUltima);
for (int i = 0; i < 100; i++) {
     //I need something like mtx[0][i] = someValue;
}

Answer 1

¡¡I DID IT!! I share it:

CvMat mtx = new CvMat(iplUltima);   

for (int i = 0; i < 100; i++) {
    for (int j = 0; j < 100; j++) {
         opencv_core.cvSet2D(mtx, i, j, CvScalar.ONE);
    }
}
iplUltima = new IplImage (mtx); 

Where i = row and j = column
