RDIR Enhanced - Examples of use
This script demonstrates how to use the different abilities of the enhanced rdir function.
Examples are based on matlabroot directory content. Results may vary depending on your version of Matlab.

Optional 2nd rdir output indicates common path removed from each output name

Using a filter with "regexp"
List ".mat" files, then select those whose name match regular expression 'data\d' (ie "data" followed by a numeric digit)
rdir([matlabroot '\toolbox\**\*.mat'], 'regexp(name, ''data\d'')', true)

Specific display - No item matching filter
When some items match input path, but none match filter, a specific message is displayed.
rdir(matlabroot, 'strcmp(name, ''unknowtoolbox'')', 1)
No item matching filter.
Specific display - Wrong filter
A warning is displayed after the non-filtered result list if entered filter is wrong.
rdir(matlabroot, 'wrong filter', 1) % EOF
