MATLAB: 2d scan plot in matlab

2d plotsscan plots

Hi,

I want to scan over 2 quantities lets say x and y. For every value of x, I scan over a range of y and record value z for every point. So I have an (x,y) grid and have z which is an x by y matrix. How would I do a 2D plot of over such quantities. Many thanks for any lead.
