13 asymreg.cc In this example a standard eigenvalue problem
14 is solved using the regular mode.
15
16 asymshft.cc In this example a standard eigenvalue problem
17 is solved using the shift and invert mode.
18
19 asymgreg.cc In this example a generalized eigenvalue problem
20 is solved using the regular mode.
21
22 asymgshf.cc In this example a generalized eigenvalue problem
23 is solved using the shift and invert mode.
24
25 asymgbkl.cc In this example a generalized eigenvalue problem
26 is solved using the buckling mode.
27
28 asymgcay.cc In this example a generalized eigenvalue problem
29 is solved using the Cayley mode.

322) Compiling the examples:
33
34 To compile and link all the above mentioned programs you just have
35 to type "make all". Each example can also be compiled separately by
36 using a specific command, such as "make asymgshf".
37
38 Because the examples that use invert modes require the solution of
39 some linear systems, the SuperLU library must be installed prior to
40 compiling asymshf, asymgreg, asymgshf, asymgbkl and asymgcay.
41
42
433) Running the examples:
44
45 A program is executed by just typing its name (asymgshf, for
46 example).
