To prevent repetitively adjust the format of plots each time, you can create "startup.m" in the startup directory of Matlab. The file will be run first when you run Matlab. The following is the example code for formatting plots.
set(groot,'defaultAxesFontName', 'Arial', ... 'DefaultAxesFontSize', 16, ... 'DefaultAxesXMinorTick', 'on', ... 'DefaultAxesYMinorTick', 'on', ... 'DefaultLineLineWidth', 1, ... 'DefaultFigurePosition', [100, 100, 750, 550]);
