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:
- 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];
