        "description": "# PseudoPy [![Build Status](https://travis-ci.org/andrenarchy/pseudopy.png?branch=master)](https://travis-ci.org/andrenarchy/pseudopy)\n\nPseudoPy computes and visualizes the pseudospectrum of a matrix. It is a Python version of the original [eigtool](http://www.cs.ox.ac.uk/pseudospectra/eigtool/) by Thomas G. Wright. The algorithms used in this package can be found in the book [Spectra and pseudospectra](http://press.princeton.edu/titles/8113.html) by [Nick Trefethen](http://www.maths.ox.ac.uk/people/profiles/nick.trefethen) and [Mark Embree](http://www.caam.rice.edu/~embree/).\n\n## Example\nThe pseudospectrum of the Grcar matrix looks like this:\n\n![Pseudospectrum of Grcar matrix](grcar.png)\n\nIf no knowledge about the location of the pseudospectrum of the given matrix is available, the following lines of code can be used to obtain an approximation:\n```python\nfrom pseudopy import NonnormalAuto, demo\nfrom matplotlib import pyplot\nfrom scipy.linalg import eigvals\n\n# get Grcar matrix\nA = demo.grcar(32).todense()\n\n# compute pseudospectrum for the levels of interest between [1e-5, 1]\npseudo = NonnormalAuto(A, 1e-5, 1)\n\n# plot\npseudo.plot([10**k for k in range(-4, 0)], spectrum=eigvals(A))\npyplot.show()\n```\n\n## Installation\n### Dependencies\nPseudoPy depends on numpy, scipy, matplotlib and shapely. If you are on Debian/Ubuntu, you can install these dependencies with\n```\nsudo apt-get install python-numpy python-scipy python-matplotlib python-shapely\n```\n\n### pip\n```pip install pseudopy```\n\nNote that you may need to add `sudo` if you want to install it system-wide.\n\n## License\nPseudoPy is free software licensed under the [MIT License](http://opensource.org/licenses/mit-license.php).",
