Hi,

After I create a matrix and try to display it with imshow, only the points with gray level 0 and 256 are displayed correctly. Other points are all displayed as white or balck.But when I use pixval to check the gray level for a particular point, the gray level value is correct. I don't know why. Pl. help. (The problem is trivial but I'm a newcomer)

Thanks a lot

Hi,
Did you enter a colormap as a second argument?
Use: imshow(X,[]) % X is your matrix
to let the function choose it for you, or: imshow(X,gray(256))
