% the m-file is created by MatlabCorner.COM
% The m-file calculates the difference between the largest
% and smallest element in vector q.
function r=range(q) % defines a function file range.m
qmax=max(q); % finds the maximum value in the vector q.
qmin=min(q); % finds the minimum -value in the vector q.
r=qmax-qmin; % gives the value that should be returned.

Save the as range.m. Now please enter a vector q=[ 1 3 5 7 9] in the command window. Run the by simply writing range(q) after the prompt in the command window.
