## psb_gedots -- Generalized Dot Product

This subroutine computes a series of dot products among the columns of two dense matrices and :

If the matrices are complex, then the usual convention applies, i.e. the conjugate transpose of is used. If and are of rank one, then is a scalar, else it is a rank one array.
