| Dataset download of real world datasets: prdatasets |
On the PRTools website a number of example datasets has been made available. They can easily be downloaded by the command
This command just checks whether a directory prdatasets is already in the path. If it is, the contents are displayed, if not the user is given the opportunity to download the prdatasets directory and the related m-files. Every dataset has its own command to load it. If it is not yet available in the prdatasets directory it is downloaded from the website.
Some of these datasets are made available by the Delft Pattern Recognition Laboratory, others are the PRTools versions of public domain datasets. 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 datasets is listed. The set may be extended.
