Re: 3-dimensional array/matrix in oct-file: crashes

[marcimatz]

Thank you Mike.

I also tried that. No luck either.
Following is my code:

if (RgbImage)
{ // RGB. Crashes in the loop
        dim_vector dv (3);
        dv(0) = resolution[0];
        dv(1) = resolution[1];
        dv(2) = 3;
        NDArray mat(dv);
        for (int i=resolution[0]-1; i>=0; i--)
        {
                for (int j=0; j<resolution[1]; j++)
                {
                        for (int k=0;k&lt;3;k++)
                                mat(i,j,k) = image[pos++]; // image is a valid 
array. Even with
mat(i,j,k)=0; is crashes!
                }
        }
}
else
{ // Greyscale. Doesn't crash and diesplays a correct greyscale image with:
imshow(mat);
        dim_vector dv (2);
        dv(0) = resolution[0];
        dv(1) = resolution[1];
        Matrix mat(dv);
        for (int i=resolution[0]-1; i>=0; i--)
        {
                for (int j=0; j<resolution[1]; j++)
                        mat(i,j) = image[pos++]; 
        }
}

While the code for the RGB image crashes Octave, the code for the greyscale
image works perfectly and displays a correct image. The initial 'image'
buffer is not the culprit, even when I take it out of the loop, it crashes.
What can it be?
