Hello,

Where exactly can I find detailed documentation or sample programs about how to utilize the eigensolver functions/routines in MAGMA?

If I plan to use MAGMA on Keeneland, how should I compile the program and submit the job?

Thanks,

Yuhao

Symmetric or non-symmetric eigen problem? Generalized problem (i.e., Ax = lambda B x)?

For symmetric problems, the routines are ssyev, dsyev, cheev, zheev (symmetric eigenvalue or hermitian eigenvalue).

For non-symmetric problems, the routines are sgeev, dgeev, cgeev, zgeev (general eigenvalue).

The documentation is in the source files, e.g.,

src/dsyev.cpp

or available online at

http://icl.cs.utk.edu/magma/docs/

under Files > File list > magma-1.4.0 > src > dsyev.cpp

The best examples are in the testing directory, e.g.,

testing/testing_dsyev.cpp

-mark

Thank you very much, this is so helpful.
