[petsc-users] About finding the eigenvalues of of large sparse matrices using SLEPc package

[Afrah Najib]

Hi,

I want to use SLEPc to find the eigenvlaues of matrices from FLorida sparse
matrix collection (https://sparse.tamu.edu/). The available matrix formats
are mtx, matlab and Rutherford Boeing.

I installed the slepc-3.11.1 successfully with petsc-lite-3.11.2 as a
dependency
How can I use the examples of this library with such matrix formats,

Many thanks for any kind of help,
