Andy and Nicholas thanks,
I have to study the manual but in the meantime....
any script or tutorial on mathematical deformation of images with Octave?
With
I = imread('c:\users\ax\desktop\_math\sfera.jpg');
S = conv2 (I, ones (5, 5) / 25, "same");
[Dx, Dy] = gradient (S);
I get error:
" error: invalid conversion of uint8 matrix to Matrix "
