ARPACK, de sus siglas en inglés ARnoldi PACKage, es una biblioteca de programación escrita en FORTRAN 77 para resolver numéricamente problemas de autovalores de gran escala. [1]
The package is designed to compute a few eigenvalues and corresponding
eigenvectors of large sparse or structured matrices, using the
Implicitly Restarted Arnoldi Method (IRAM)
or, in the case of symmetric matrices, the corresponding variant of the
Lanczos algorithm.
Reverse Communication Interface
editarA powerful feature of ARPACK is its ability to use any matrix storage format. This is possible because it doesn't operate on the matrices directly, but instead when a matrix operation is required it returns control to the calling program with a flag indicating what operation is required. The calling program must then perform the operation and call the ARPACK routine again to continue. The operations are typically matrix-vector products, and solving linear systems.
