1function n2 = dist2(x, c)
2%DIST2 Calculates squared distance between two sets of points.
3%
4% Description
5% D = DIST2(X, C) takes two matrices of vectors and calculates the
6% squared Euclidean distance between them. Both matrices must be of
7% the same column dimension. If X has M rows and N columns, and C has
8% L rows and N columns, then the result has M rows and L columns. The
9% I, Jth entry is the squared distance from the Ith row of X to the
10% Jth row of C.
