Put all of your help text in comments at the top of the file. E.g., here is a file called mycube.m

% MYCUBE Calculates the cube of each element
% Syntax:
%   Y = mycube(X)
% where
%   X = any numeric variable
%   Y = array the same size as X, with each element cubed.
function Y = mycube(X)
Y = X.^3;
end

Note that a short description in the first line using key words enables this function to be found with the "lookfor" function.

>> help mycube

    Y = mycube(X)
