This function will usually compute the standard dot product of vectors
x and y, (x,y)=y^H x. However this behaviour may be different if changed
via <A HREF="../IP/IPSetMatrix.html#IPSetMatrix">IPSetMatrix</A>(). This allows use of other inner products such as
the indefinite product y^T x for complex symmetric problems or the
B-inner product for positive definite B, (x,y)_B=y^H Bx.
