Function rgsl::blas::level2::ssyr

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

This function computes the symmetric rank-1 update A = \alpha x x^T + A of 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.
