%MATLABRC Master startup MATLAB script.
%   MATLABRC is automatically executed by MATLAB during startup.
%   It sets the default figure size, and sets a few uicontrol defaults.
%
%   On multi-user or networked systems, the system manager can put
%   any messages, definitions, etc. that apply to all users here.
%
%   A STARTUP command is invoked after executing MATLABRC if the file 'startup.m'
%   exists on the MATLAB path.
