libhmat suggestion: dot product between vectors

[eunnieverse]

The following operations for HVector datatype will be useful.

dot product between vectors complex conjugate for all elements

[HomerReid]

In 5fd499bdae3bd232e16ef54f27bf198ff87a8b11 there are some new routines:

cdouble HVector::Dot(HVector *B);   /* hermitian dot product, this \cdot B */
cdouble HVector::DotU(HVector *B);  /* non-conjugated dot product */
double  HVector::DotD(HVector *B);  /* real part of Dot()       */

Also, HMatrix has a matrix-vector multiplication method:

   /* matrix-vector multiplication, this*X = Y (xgemv))      */
   /* Trans='C' or 'T' for hermitian / non-hermitian adjoint */
   void HMatrix::Apply(HVector *X, HVector *Y, char Trans=0);

(All of these routines are just wrappers around the level-1 and level-2 BLAS). Please let me know how they work.

Row * Matrix * Vector operations can be simplified with HVector::Dot / HVector::DotU and HMatrix::Apply. Thank you! The issue is now closed.
