This command is used to perform the analysis.

analyze <$type> <$solver> $numEigenvalues

$numEigenvalues number of eigenvalues required
$type optional string detailing type of eigen analysis, -standard of -generalized (default generalized)
$solver optional string detailing type of solver, -UmfPack, -genBandArpack, -symmBandLapack, -SuperLU (default genBandArpack)


RETURNS:

a tcl string containg eigenvalues.


NOTES:

  1. The eigenvectors are stored at the nodes and can be printed out using a Node Recorder, the nodeEigenvector command, or the Print command.



EXAMPLE:

set eigenvalues [eigenvalue 10];
