Hi, thank you very much for this! I will look through it all now :)

Great, thank you very much for your help! :)

Thank you, can you just clarify what you mean by their indexes?

I assume here fft means fast Fourier transform? I'm not sure if that's different, or if I should be expecting the same result. If so, then now I know what to expect, so thanks :) but I'm still stuck on trying to plot the real components of the array and the complex ones, and whether or not they...

Ok thank you, how do I plot both the real and imaginary parts of an array? I suppose you mean, say an element is x + iy, I'm plotting x vs y for every element? I'm not sure how to go about this. Thanks again

Hi, thanks for the suggestion, but it's for an assignment and so we've been told to perform this specific test as part of the assigment.

Homework Statement I've written a program that calculates the discrete Fourier transform of a set of data in FORTRAN 90. To test it, I need to "generate a perfect sine wave of given period, calculate the DFT and write both data and DFT out to file. Plot the result- does it look like what you...
