I am dissapointed. I recently upgraded to Maple 15 and I bought a license for the NAG libraries thinking that I could use NAG mark 8 chapter F12 to solve my Eigenvalue problem with large sparse matrix, in reality, there seems to be no implementation of these NAG routines in Maple. is there a way to get around this problem? I know I can also connect to MATLAB to take advantage of the integrated sparse handling but I want to avoid buying another piece of software(you know we scientist aren't millionaries).
Eigenvalue solving for large sparse matrices is a very common problem in quantum physics of many body systems, I can't understand why it is something Maple does not handle it. I suppose it's because most people working on this area are programming in C or Fortran?
