Develop a MATLAB script to plot the function

where ω is a variable input at the command prompt. Label the x-axis with time (sec) and the y-axis with y(x) = (4/π) * cos(ωx) + (4/9π) * cos(3ωx). Include a descriptive header in the script, and verify that the help function will display the header. Choose ω = 1, 3,10 rad/s and test the script.
