getPatch; matlab function to get a patch from a matrix

function mat = getPatch(srcMat, rect)
%function getPatch(srcMat, rect)
%rect is [x y width height]

stX = max(rect(1),1);stY = max(rect(2),1);
endX = min(rect(1)+rect(3)-1, size(srcMat,1));endY = min(rect(2)+rect(4)-1, size(srcMat,2));
mat = srcMat(stY:endY, stX:endX);
