** Residue of a repeated pole. **

** RESI2(U,V,POLE,N,K) returns the residue of a repeated pole **

** of order N and the K-th power denominator of [1 -pole], where **

** U and V represent the original polynomial ratio U/V. **

** For example, if P is a pole of multiplicity 2, **

** then this routine should be called twice with N = 2, **

** first using K = 1, then K = 2. If K is not provided, **

** it defaults to N. If N is not provided, it defaults to 1. **
