Function rgsl::blas::level2::chemv

pub fn chemv(
    uplo: CblasUplo, 
    alpha: &ComplexF32, 
    A: &MatrixComplexF32, 
    x: &VectorComplexF32, 
    beta: &ComplexF32, 
    y: &mut VectorComplexF32
) -> Value

These functions compute the matrix-vector product and sum y = \alpha A x + \beta y for the hermitian matrix A. Since the matrix A is hermitian 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. The imaginary elements of the diagonal are automatically assumed to be zero and are not referenced.
