BlasL2GeR

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

AU = alpha*x*y + A

BLAS functions GER, GERU.

Computing for type matrix<double>

bool  matrix::BlasL2GeR(
   double          alpha,         // scalar multiplier alpha
   vector&         X,             // vector X
   vector&         Y,             // vector Y
   matrix&         AU             // updated matrix A
   );

Computing for type matrix<float>

bool  matrixf::BlasL2GeR(
   float           alpha,         // scalar multiplier alpha
   vectorf&        X,             // vector X
   vectorf&        Y,             // vector Y
   matrixf&        AU             // updated matrix A
   );

Computing for type matrix<complex>

bool  matrixc::BlasL2GeR(
   complex         alpha,         // scalar multiplier alpha
   vectorc&        X,             // vector X
