Function rgsl::blas::level3::zherk

pub fn zherk(uplo: Uplo, trans: Transpose, alpha: f64, A: &MatrixComplexF64, beta: f64, C: &mut MatrixComplexF64) -> Value

These functions compute a rank-k update of the hermitian matrix C, C = \alpha A A^H + \beta C when Trans is NoTrans and C = \alpha A^H A + \beta C when Trans is ConjTrans. Since the matrix C is hermitian only its upper half or lower half need to be stored. When Uplo is Upper then the upper triangle and diagonal of C are used, and when Uplo is Lower then the lower triangle and diagonal of C are used. The imaginary elements of the diagonal are automatically set to zero.
