This is the arpack++/examples/product/nonsym directory.1) Examples included in this directory: This directory contains examples intended to show how to use ARPACK++ to solve real nonsymmetric eigenvalue problems in various computational modes when the user is able to supply some classes that contain all required matrix-vector products as member functions. file Description ----------- -------------------------------------------------- nsymreg.cc In this example a standard eigenvalue problem is solved using the regular mode. nsymshf.cc In this example a standard eigenvalue problem is solved using the shift and invert mode. nsymgreg.cc In this example a generalized eigenvalue problem is solved using the regular mode. nsymgshf.cc In this example a generalized eigenvalue problem is solved using the real shift and invert mode. nsymgscr.cc In this example a generalized eigenvalue problem is solved using the complex shift and invert mode (considering only the real part of inv(A-sigmaB)). nsymgsci.cc In this example a generalized eigenvalue problem is solved using the complex shift and invert mode (considering only the imaginary part of inv(A-sigmaB)). svd.cc In this example ARPACK++ is used to obtain a few singular values of a real nonsymmetric matrix.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 nsymgshf".3) Running the examples: A program is executed by just typing its name (nsymgshf, for example).
