A "discrete" contour plot

If M(i,j) is a matrix,
How might I plot a contour plot where the (i,j) point on the x,y-plane has altitude M(i,j)?
What I did was
x = 1:1:imax;
y = 1:1:jmax;
[x,y] = meshgrid(x,y);
z=M;
[c,h] = contour(x,y,z,100);
clabel(c,h,'manual');
But it doesn't seem to be right…
(If the plotting bit is right, then there must be something else the wrong with the program!)

It isn't a good idea to overwrite x and y with meshgrid(x,y), in the sense that it is confusing to the reader.

When you say "discrete" contour plot, do you mean something like
z = abs(round(peaks(5)));
bar3(z,0.3);
