Function rgsl::blas::level2::dgemv

pub fn dgemv(
    transA: Transpose,
    alpha: f64,
    A: &MatrixF64,
    x: &VectorF64,
    beta: f64,
    y: &mut VectorF64
) -> Value

This function computes the matrix-vector product and sum y = \alpha op(A) x + \beta y, where op(A) = A, A^T, A^H for TransA = CblasNoTrans, CblasTrans, CblasConjTrans.
