**ACTION:**- From the
**W**and**V**matrices from the SVD factorization of a matrix (as obtained from the sla_SVD routine), obtain the covariance matrix. **CALL:**`CALL sla_SVDCOV (N, NP, NC, W, V, WORK, CVM)`

**GIVEN:**-

*N***I***n*, the 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 CVM *W***D(N)**diagonal matrix **W**(diagonal elements only)*V***D(NP,NP)**array containing orthogonal matrix **V**

**RETURNED:**-

*WORK***D(N)**workspace *CVM***D(NC,NC)**array to receive covariance matrix
