I'm sorry for the basic part, but it's a similar question, but when I searched for which package I needed for Fourier transform, it didn't hit me, and I only wrote about using it smoothly on the Internet.
plan_ft (one-dimensional array) or ft (one-dimensional array)
Even if I use , both of them are not defined...
Since Julia doesn't have much information, I'd like to ask you a question here.
It would be very helpful if someone could tell me.
Perhaps you need to install AbstractFFTs.jl.Specifically, using Pkg and Pkg.add("AbstractFFTs") download and install files from the GitHub repository. If you want to use ft() or plan_ft(), run using Abstract.
