Dear Matt,
I understood that you are right. I changed sizeof(values) with ncols, it
gives matrix correctly.
However, now I get an error in EPSGetEigenpair:
0]PETSC ERROR: - Error Message

[0]PETSC ERROR: Argument o
Dear Matt,
I printed in wrong state, ncols gives right solution.
But I still can't understand the first problem.

Dear Matt,
Thank you for answering. First of all, sizeof(vals) returns to number of
entries, I checked. Secondly, I found a problem:
ncols gives me 6.95328e-310. However, I checked the matrix L, it was
computed properly.
Why can ncols give such a value?
Thanks,
Eda

Hello,
I have a following part of a code which tries to change the nonzero values
of matrix L with -1. However in MatSetValues line, something happens and
some of the values in matrix turns into 1.99665e-314 instead of -1. Type of
arr is defined as PetscScalar and arr is produced correctly. What c
