Inverse of complex diagonal matrix

Fri Jan 13, 2012 10:21 pm
I have defined:
Code: Select all
VectorXcd V(5);
   V(0)=alphax; //assign complex (double) number
   V(1)=alphay; //assign complex (double) number
   V(2)=alphaz; //assign complex (double) number
   V(3)=0;
   V(4)=0;
   MatrixXcd M(5,5);
   M=V.asDiagonal();


How could I obtain the inverse of the complex diagonal matrix?
Thanks

M=V.asDiagonal().inverse();
