Detailed Description

Sparse matrix-vector multiply implementation.

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

#include <oski/common.h>
#include <oski/matrix.h>

Functions

int oski_CheckArgsMatMult (const oski_matrix_t A_tunable, oski_matop_t opA, oski_value_t alpha, const oski_vecview_t x_view, oski_value_t beta, const oski_vecview_t y_view, const char *caller)
 Checks validity of arguments to a routine with a matrix vector multiply signature.
int oski_MatMult (const oski_matrix_t A_tunable, oski_matop_t opA, oski_value_t alpha, const oski_vecview_t x_view, oski_value_t beta, const oski_vecview_t y_view)
 Computes $y \leftarrow \alpha\cdot\mathrm{op}(A)x + \beta\cdot y$, where $\mathrm{op}(A) \in \{A, A^T, A^H\}$.
