qforms-tk: Matlab toolbox to analyze quadratic forms
Update (3.4.2006)It turns out that a previous version of qforms-tk was missing the routine that implements the Gram-Schmidt orthogonalization algorithm. This has been fixed in the current version!
Introductionqforms-tk is a Matlab toolbox to analyze quadratic forms. It contains the algorithms described in
Berkes, P. and Wiskott, L. (2005).
On the analysis and interpretation of inhomogeneous quadratic forms as receptive fields.
Neural Computation, accepted.
In the toolbox you'll finda demo script that shows how to compute and visualize the optimal stimuli and the invariances of a quadratic form.
This program has been written by Pietro Berkes.
Download and InstallationThe package has been tested on Matlab 188.8.131.5201 (R14).
.tgz (ca. 0.5 Mb): qforms_tk.tgz
To install it, simply unpack the archive into your favorite Matlab
directory. This is going to create a
directory. Before you begin to use the functions, make sure that the
qforms_tk/qform directory is in your Matlab path.
qforms-tk/demo directory you will find an example
quadratic form and a script that shows hot to compute and visualize
the optimal stimuli and the invariances.
