I have a 2D matrix , and I was trying to display it as an image, but the problem is that in the output axes, for all the numbers except 0, I see white in result, and black for zero, I want to see all gray colors (in grayscale) from black to white, what can I do? this is the resault I see

It's probably a type double, which needs to be in the range 0-1, not 0-255 that you probably have. You can autoscale with []. Try
imshow(your2Dmatrix, []);
