matlabrc.m

%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.
%
%   如果在 Matlab path 中存在 'startup.m' 文件，在执行完 MATLABRC 后再执行 STARTUP 命令。
