Controlling plot data-tips
Data-tips are an extremely useful plotting tool that can easily be controlled programmatically.
Bug and workaround in timeseries plot
Matlab's internal hgconvertunits function has a bug that affects timeseries plots. Luckily there is a simple workaround.
Uitable sorting
Matlab's uitables can be sortable using simple undocumented features
Hierarchical Systems with UDD
