MATLAB: Divide a Sphere surface into equal ares

You will have X,Y,Z matrices as coordinates of sphere. Let its size be mxn. You divide these matrices into m/pxn/p sub matrices of p in number. So that all submatrcies have equal dimensions. Then they would be having equal areas. Use reshape to divide into sub matrices.

MATLAB: How to fit a square and find the center point

If your points are the rows of a matrix P, then

 lowerleftCorner=min(P);
 upperrightCorner=max(P);
 center = lowerleftCorner/2 + upperrightCorner/2;

This will give you the corners of the tightest, non-rotated rectangle around the points. If you really do want a square and not a rectangle, you can enlarge one of the sides of the rectangle.
