A Julia package to support forward-mode auto-differentiation for fast transforms
A package for forward-mode auto-differentiation for fast transforms. Currently supports the fft:
julia> using FastTransformsForwardDiff: derivative
julia> θ = range(0,2π; length=n+1)[1:end-1];
julia> derivative(ω -> fft(exp.(ω .* cos.(θ)))[1]/n, 1)
