void gemv(char transpose, IdxT k, const ScalarT alpha, const ScalarT beta, Vector<ScalarT, IdxT> *V, Vector<ScalarT, IdxT> *y, Vector<ScalarT, IdxT> *x)

gemv: if transpose = N (no), x = beta*x + alpha*V*y, where x is [n x 1], V is [n x k] and y is [k x 1]. if transpose = T (yes), x = beta*x + alpha*V^T*y, where x is [k x 1], V is [n x k] and y is [n x 1].
