PETSc & SLEPc Example

PETSc (Protable, Extensible Toolkit for Scientific Computation) is a suite of data structures and routines to solve partial differential equations for scientific applications, whilst employing parallelism to scale the computation. SLEPc (Scalable Library for Eigenvalue Problem Computations) is able to solve linear & nonlinear eigenvalue problems, action of a matrix function on a vector, and perform singular value decomposition.

This example job solves a singular value problem on the matrix loaded from a file.
