Function rgsl::blas::level2::ssymv

pub fn ssymv(uplo: Uplo, alpha: f32, A: &MatrixF32, x: &VectorF32, beta: f32, y: &mut VectorF32) -> Value

These functions compute the matrix-vector product and sum y = \alpha A x + \beta y for the symmetric matrix A. Since the matrix A is symmetric only its upper half or lower half need to be stored. When Uplo is CblasUpper then the upper triangle and diagonal of A are used, and when Uplo is CblasLower then the lower triangle and diagonal of A are used.
