[petsc-users] SLEPC matrix Query

[Savneet Kaur]

Hello,

Warm Regards

I am Savneet Kaur, a master student at University Paris Saclay and 
currently pursuing an internship at CEA Saclay (France).

I have recently started to understand the slepc and petsc solvers, by 
taking up the tutorials for eigenvalue problems. In my internship work I 
have to develop a laplacian matrix from a given transition rate matrix 
and solve it using SLEPC and PETSC and to evaluate the lowest eigenvalue.

I was wondering if I could get some information. I need to diagonalize a 
2D Laplacian matrix. And writing a code in C and diagonalizing it is 
easy. But I am not getting it how to accommodate with the SLEPC Program. 
Am i suppose to use any packages or it will is done by a loop? Or I need 
to read some other manual to understand how does it work. Please kindly 
let me know.

The diagonalizing a matrix will be preliminary step of my work.

I will be highly obliged to the the team, if I could get help.

Hoping for a favorable response from your side.

Thank you for the time and consideration.


Sincerely,
