MATLAB: Is there a way to define a new built-in function

built-infunctionMATLABplotplottingrgb

Greetings,

For plotting purposes, I simply want to have a built-in function that gives you the color of your choice. Code is well written and ready, however, I wonder if there is a way to make it built-in instead of including the .m file where ever I need.

Any advice is most appreciated.

I'm under the vague impression that you are unaware of the Matlab path and how it allows you to keep your mfiles in one place where Matlab can find them. See addpath and pathtool.

If you have downloaded an M-file, then you need to add the folder (directory) in which that M-file lives to the MATLAB path, otherwise MATLAB cannot find it.

use the addpath() command, or pathtool

For example, if the file is located in c:\mfiles

 >>addpath('c:\mfiles')

Or just enter:

>>pathtool

and add the folder.

This should work regardless if your current folder is the one that contains your m-file, or not.

% Determine where your m-file's folder is.
folder = fileparts(which(mfilename)); 
% Add that folder plus all subfolders to the path.
addpath(genpath(folder));
