BLAS Level 1: rotmg, rotm

rotmg, rotm are defined in namespace flens::blas.

rotmg

template <typename T, typename VP>
    void
    rotmg(T &d1, T &d2, T &b1, T &b2, DenseVector<VP> &p);

rotm

template <typename VX, typename VY, typename VP>
    typename RestrictTo<IsDenseVector<VX>::value
                     && IsDenseVector<VY>::value,
             void>::Type
    rotm(VX &&x, VY &&y, const DenseVector<VP> &p);

Defined in namespace flens::blas. Function rotm with 3 template parameters.

x

(input/output) real or complex DenseVector
On exit, contains the rotated \(x\)-coodrinates.

y

(input/output) real or complex DenseVector
On exit, contains the rotated \(y\)-coodrinates.

c

(input) real or complex scalar
The parameter \(c\) associated with the Givens rotation.
