This is the arpack++/examples/umfpack/complex directory.
1) Examples included in this directory:
This directory contains examples intended to show how to use
ARPACK++ to solve complex eigenvalue problems in various
computational modes in conjunction with the UMFPACK library.
file Description
----------- --------------------------------------------------
ucompreg.cc In this example a standard eigenvalue problem
is solved using the regular mode.
ucompshf.cc In this example a standard eigenvalue problem
is solved using the shift and invert mode.
ucompgre.cc In this example a generalized eigenvalue problem
is solved using the regular mode.
ucompgsh.cc In this example a generalized eigenvalue problem
is solved using the real shift and invert mode.
2) Compiling the examples:
To compile and link all the above mentioned programs you just have
to type "make all". Each example can also be compiled separately by
using a specific command, such as "make ucompgsh".
Because the examples that use invert modes require the solution of
some linear systems, the UMFPACK library must be installed prior to
compiling ucompshf, ucompgre and ucompgsh.
3) Running the examples:
A program is executed by just typing its name (ucompgsh, for
example).
