Docking Matlab Figures

To dock the figure window in Matlab, create a file named startup.m in Matlab's default directory and add the following line.
set(0,'DefaultFigureWindowStyle','docked')

In case you don't know where the default directory is, open Matlab and enter the command pwd in the command window.

To revert the docking behavior, either change the line in startup.m to
set(0,'DefaultFigureWindowStyle','normal')

or delete startup.m.
