a graphical tool for nonsymmetric eigenproblems
EigTool is a free MATLAB package for computing pseudospectra of dense and sparse matrices.
It also provides a graphical interface to MATLAB's built-in eigs routine
(ARPACK) for large-scale eigenvalue
computations. EigTool was developed from 1999 - 2002 by Thomas G. Wright at the
Oxford University Computing Laboratory, under the direction of
The software is presently maintained by Mark Embree
(Rice University), to whom any bug reports or other suggestions should be addressed.
