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.
