Hi everyone, how can I make the time derivative property of the fourier transform? Can you show an example?

What I am working on is similar to the mathematical processes in this article. The matrix is ​​created by taking the fourier transformations of rate equations 1-5 in the article (by using the time derivative property of fourier transform). When I apply these mathematical processes to my own work, I do not get the results I expect. Parts where I made mistakes: 1) Creating the frequency vector denoted by w 2) The stage of amplitude normalization in Fourier transform

Can you show just the relevant parts of your code for a simple example? Doesn't have to be for the actual equation, just a simple case where we know what the result should be.

You cannot -- the fourier transform is based on frequency rather than time.
