imHistogram

Generic function for computing histogram of an image. Image can be either 2D or 3D, grayscale or color. For color images, the result is the concatenation of the histogram computed for each band.

If no output is requested, the histogram is plotted on the current axis.

Several options can be applied, like min and max levels to consider, number of histogram bins, location of bin centers, region of interest.
