Detailed Description

Implementation of simultaneously multiplication by sparse $A$ and $\mathrm{op}(A) \in \{A, A^T, A^H=\bar{A}^T\}$ .

This module implements the matrix type-independent version, which performs error-checking first and then calls the the appropriate kernel implementation.

static int MatMultAndMatTransMultDefault	(	const oski_matrix_t	A_tunable,
		oski_value_t	alpha,

		oski_value_t	zeta,
		oski_vecview_t	z
	)		`[static]`

A default implementation of simultaneous multiplication by sparse $A$ and $\mathrm{op}(A)$ based on multiple calls to sparse matrix-vector multiply.

This implementation provides a fall-back code in the event that no tuned implementation exists.

Precondition:: A_tunable != INVALID_VEC

Verifies arguments to oski_MatMultAndMatTransMult.

Verify the arguments to a function with a calling signature like oski_MatMultAndMatTransMult().

Returns:: 0 if all arguments are OK, or an error code (plus a call to the error handler) otherwise.
