Function rgsl::blas::level3::zsyr2k

pub fn zsyr2k(
    uplo: CblasUplo, 
    trans: CblasTranspose, 
    alpha: &ComplexF64, 
    A: &MatrixComplexF64, 
    B: &MatrixComplexF64, 
    beta: &ComplexF64, 
    C: &mut MatrixComplexF64
) -> Value

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