SUBSPACE Angle between two subspaces.
	SUBSPACE(A,B) finds the angle between two subspaces specified
	by the columns of A and B.  If A and B are vectors of unit
	length, this is the same as ACOS(A'*B).
	If the angle is small, the two spaces are nearly linearly
	dependent.  In a physical experiment described by some
	observations A, and a second realization of the experiment
	described by B, SUBSPACE(A,B) gives a measure of the amount
	of new information afforded by the second experiment not
	associated with statistical errors of fluctuations.
