STK_DIST computes a matrix of (Euclidean) distances

 CALL: D = stk_dist(X, Y)

    computes the matrix of distances between X and Y. More precisely, if
    X is an nX x d matrix, and Y an nY x d matrix, the D is an nX x nY
    matrix with

       D_{i,j} = norm(X(i,:) - Y(j,:)),

    where norm(.) denotes the Euclidean norm in R^d.
