c=operatoreigs(Op,K);
[V,D]=operatoreigs(Op,K) computes the K largest eigenvalues and eigenvectors of the operator Op to the input signal f. The operator object Op must have been created using operatornew.
If K is empty, then all eigenvalues/pairs will be returned.
D=operatoreigs(...) computes only the eigenvalues.
operatoreigs takes the following parameters at the end of the line of input arguments:
| 'tol',t | Stop if relative residual error is less than the specified tolerance. Default is 1e-9 |
| 'maxit',n | Do at most n iterations. |
| 'iter' | Call eigs to use an iterative algorithm. |
| 'full' | Call eig to solve the full problem. |
| 'auto' | Use the full method for small problems and the iterative method for larger problems. This is the default. |
| 'crossover',c | Set the problem size for which the 'auto' method switches. Default is 200. |
| 'print' | Display the progress. |
| 'quiet' | Don't print anything, this is the default. |
