Dear sir; I downloaded this package but I do not know how to install it. I did not see instructions on installation. I am interested in learning more about fourier analysis for my Electrical Power class. Thanks.

Thanks a lot! I have a graph now. Some operations are not that intuitive at least to me. Thanks again for your time.
