+  From the W and V matrices from the SVD factorisation of a matrix
+  (as obtained from the slSVD routine), obtain the covariance matrix.
+
+  (double precision)
+
+  Given:
+     N      i         number of rows and columns in matrices W and V
+     NP     i         first dimension of array containing matrix V
+     NC     i         first dimension of array to receive CVM
+     W      d(N)      NxN diagonal matrix W (diagonal elements only)
+     V      d(NP,NP)  array containing NxN orthogonal matrix V
+
+  Returned:
+     WORK   d(N)      workspace
+     CVM    d(NC,NC)  array to receive covariance matrix
