Introduction
In this tutorial we learn how to install arpack on CentOS 8.
What is arpack
ARPACK is a collection of Fortran 77 subroutines designed to solve large scale eigenvalue problems. The package is designed to compute a few eigenvalues and corresponding eigenvectors of a general n by n matrix A. It is most appropriate for large sparse or structured matrices A where structured means that a matrix-vector product w <- Av requires order n rather than the usual order n**2 floating point operations. This software is based upon an algorithmic variant of the Arnoldi process called the Implicitly Restarted Arnoldi Method (IRAM).
We can use yum or dnf to install arpack on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install arpack.
