Function Documentation

int rc_matrix_times_col_vec(rc_matrix_t A, rc_vector_t v, rc_vector_t *c)

Multiplies matrix A times column vector v and places the result in column vector c.

Any existing data in c is freed if necessary and c is resized appropriately. Vectors v and c are interpreted as column vectors, but nowhere in their definitions are they actually specified as one or the other.

Parameters

  • A – [in] input matrix

  • v – [in] input vector

  • c – [out] output vector

Returns

Returns 0 on success or -1 on failure.
