Function rgsl::blas::level3::zsyrk

pub fn zsyrk(
    uplo: Uplo,
    trans: Transpose,
    alpha: &ComplexF64,
    A: &MatrixComplexF64,
    beta: &ComplexF64,
    C: &mut MatrixComplexF64
) -> Value

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