         Input Parameters:
    
      +  nep   - the nonlinear eigensolver context
    
      .  rg    - optional region
    
      .  omega - value where the resolvent must be evaluated

         Output Parameter:
    
      .  r     - result vector
    
         Note:
    
         The resolvent $T^{-1}(z) = \sum_i (z-\lambda_i)^{-1} x_i y_i^*$ is evaluated at
    
         $z=\omega$ and the matrix-vector multiplication $r = T^{-1}(\omega) v$ is computed.
    
         Vectors $x_i$ and $y_i$ are right and left eigenvectors, respectively, normalized
    
         so that $y_i^*T'(\lambda_i)x_i=1$. The sum contains only eigenvectors that have
    
         been previously computed with `NEPSolve()`, and if a region `rg` is given then only
    
         those corresponding to eigenvalues inside the region are considered.

86			Collective
87
88			Input Parameters:
89			+ nep - the nonlinear eigensolver context
90			. rg - optional region
91			. omega - value where the resolvent must be evaluated
92			- v - input vector
93
94			Output Parameter:
95			. r - result vector
96
97			Note:
98			The resolvent $T^{-1}(z) = \sum_i (z-\lambda_i)^{-1} x_i y_i^*$ is evaluated at
99			$z=\omega$ and the matrix-vector multiplication $r = T^{-1}(\omega) v$ is computed.
100			Vectors $x_i$ and $y_i$ are right and left eigenvectors, respectively, normalized
101			so that $y_i^*T'(\lambda_i)x_i=1$. The sum contains only eigenvectors that have
102			been previously computed with `NEPSolve()`, and if a region `rg` is given then only
103			those corresponding to eigenvalues inside the region are considered.
