BlasL2GeRC

Performs a rank-1 conjugated update of a general m-by-n matrix.

AU = alpha * x * conjg(y) + A

BLAS function GERC.

Computing for type matrix<complex>

bool  matrixc::BlasL2GeRC(
   complex         alpha,         // scalar multiplier alpha
   vectorc&        X,             // vector X
   vectorc&        Y,             // vector Y
   matrixc&        AU             // updated matrix A
   );

Computing for type matrix<complexf>

bool  matrixcf::BlasL2GeRC(
   complexf        alpha,         // scalar multiplier alpha
   vectorcf&       X,             // vector X
   vectorcf&       Y,             // vector Y
   matrixcf&       AU             // updated matrix A
   );

Parameters
