Hi everyone, I am trying to use the Shift-and-invert spectral transformations for my diagonalisation code. While there is no problem running the code with
STSetType(st,STSHIFT); I receive the following errors when using STSetType(st,STSINVERT): [0]PETSC ERROR: --------------------- Error Message -------------------------------------------------------------- [0]PETSC ERROR: See http://www.mcs.anl.gov/petsc/documentation/linearsolvertable.html for possible LU and Cholesky solvers [0]PETSC ERROR: Could not locate a solver package.

Thank you very much! Best regards, Yang Bo
