Description

S3L_matvec_sparse computes the product of a global general sparse matrix with a global dense vector. The sparse matrix is described by the S3L array handle A. The global dense vector is described by the S3L array handle x. The result is stored in the global dense vector described by the S3L array handle y.

The array handle A is produced by a prior call to one of the following routines:

• S3L_declare_sparse

• S3L_read_sparse

• S3L_rand_sparse
