[petsc-users] all eigen values

[siddhesh godbole]

Hello ,

I am a novice in using PETSC. Right now I am solving a cantilever beam
vibration problem with PETSc in which i am using SLEPc to compute the eigen
values. But in order to diagonalize the K and M matrices i need a full
eigen matrix and all eigen values.
What i see from all the tutorial help related to SLEPc is that it computes
only certain number of eigenvalues which fall in some range or order.

Please clarify me if i am ignorant about full usage of SLEPc and kindly
suggest some way out.

sincerely
