2. Script Files Script files text files (created with a text editor) contain many lines of MATLAB expressions and assignments. You can execute all of the lines of the file (sequentially) by typing the filename at the MATLAB prompt. If filename is computetraj.m, then >> computetraj causes the instructions (ie., the MATLAB commands) in the file to be run.

3. Script file example Suppose a file called runthis.m contains the text X = linspace(0,4*pi,1000); Y = sin(3*X) + 2*cos(5*X); plot(X,Y) maxy = max(abs(Y)); disp([’Peak of Y is ’ num2str(maxy)]); Then, typing >> runthis will cause the 5 lines to execute, resulting in a plot and a message about the peak value of Y.
