arpack_test


arpack_test, a MATLAB code which calls arpack(), which computes eigenvalues and eigenvectors of large matrices. The arpack library is accessible in MATLAB via the eigs() command.

  1. help eigs
    will print out information about how to use eigs() command inside of MATLAB to interface with ARPACK.
  2. Information about the use of the ARPACK execution trace facilities available through "debug.h" is given in arpack_debug.txt
  3. Information about the use of the ARPACK operation count and timing statistics available through "stat.h" is given in arpack_stat.txt
