How To Install libarpack2 on Ubuntu 20.04
Introduction
In this tutorial we learn how to install libarpack2
on Ubuntu 20.04.
What is libarpack2
libarpack2 is:
ARPACK software is capable of solving large scale symmetric, nonsymmetric, and generalized eigenproblems from significant application areas. The software is designed to compute a few (k) eigenvalues with user specified features such as those of largest real part or largest magnitude. Storage requirements are on the order of n*k locations. No auxiliary storage is required. A set of Schur basis vectors for the desired k-dimensional eigen-space is computed which is numerically orthogonal to working precision. Numerically accurate eigenvectors are available on request.
Important Features:
- Reverse Communication Interface.
- Single and Double Precision Real Arithmetic Versions for Symmetric, Non-symmetric,
- Standard or Generalized Problems.
- Single and Double Precision Complex Arithmetic Versions for Standard or Generalized Problems.
- Routines for Banded Matrices - Standard or Generalized Problems.
- Routines for The Singular Value Decomposition.
- Example driver routines that may be used as templates to implement numerous Shift-Invert strategies for all problem types, data types and precision.
