Please write the following Matlab function:

Write the function plot_histogram that takes as input a histogram (as returned from compute histogram) and plots it similar to the plots shown below. The x-axis should range from 0 to 255 and be labeled "intensity value". The y-axis should range from 0 to the maximum value of the histogram and should be labeled "PMF" (for probability mass function).
