Description

S3L_gen_svd computes the singular value of a parallel array A and, optionally, the right and/or left singular vectors. On exit, S contains the singular values. If requested, U and V contain the left and right singular vectors, respectively.

If A, U, and V are two-dimensional arrays, S3L_gen_svd is more efficient when A, U and V are allocated on the same process grid and the same block size is used along both axes. When A, U, and V have more than two dimensions, S3L_gen_svd is more efficient when axis_r, axis_c and axis_s are local (that is, are not distributed).
