| Datafile download: prdatafiles |
A number of example datafiles has been made available. They can easily be downloaded by the command
This command just checks whether a directory prdatafiles is already in the path. If it is, the contents are displayed, if not the user is given the opportunity to download the prdatafiles directory and the related m-files. Every datafile has its own command to load it. If it is not yet available in the prdatafiles directory it is downloaded from the website.
Some of these datafiles are made available by the Delft Pattern Recognition Laboratory, others are the PRTools versions of public domain data. As far as possible the origin, links and references are given in the help files of the commands that load them.
In the below table a number available datafiles is listed. The set may be extended.
