To set a dark theme for background color, font color, font size, and plot colors in Matlab, you can customize the default settings for these elements using the following methods:

1. Dark Theme Background Color and Font Color: You can customize the background color and font color using the figure settings:

   main.m
   % Set background color to dark grey
   set(groot, 'defaultfigurecolor', [0.1 0.1 0.1]);
   
   % Set font color to white
   set(groot, 'defaultaxesfontcolor', [1 1 1]);

3. Plot Colors: You can define custom colors to suit the dark theme. For example, to set the color of plots:

   main.m
   % Define custom colors
   dark_blue = [0 0.447 0.741];
   dark_red = [0.85 0.325 0.098];
   
   % Set the default plot colors
   set(groot, 'defaultaxescolororder', [dark_blue; dark_red]);

By setting these properties, you can create a customized dark theme for your Matlab plots.

Please note that these settings will apply to all future plots created in Matlab.
