Function rgsl::blas::level3::cher2k

pub fn cher2k(
    uplo: CblasUplo, 
    trans: CblasTranspose, 
    alpha: &ComplexF32, 
    A: &MatrixComplexF32, 
    B: &MatrixComplexF32, 
    beta: f32, 
    C: &mut MatrixComplexF32
) -> Value

This function computes a rank-2k update of the hermitian matrix C, C = \alpha A B^H + \alpha^* B A^H + \beta C when Trans is NoTrans and C = \alpha A^H B + \alpha^* B^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.
