plotting a region of a matrix

I have loaded a data set into matlab, but i just want to make a surface plot a small region of the entire matrix. Right now it is a 544x512 uint16 matrix, but i just want to use the region 300/544, 200/512. how can I do this?

So far, this is the code:

colormap(hsv) surf(double(Data))

subRegion = Data(300:end, 200:end); % Extract sub-rectangle of full data.
surf(subRegion);
