How can I implement this equation?

Hello Forks

How can I implement P = A’*D ?

typeof(A)=LazyAlgebra.Composition{3,Tuple{LazyAlgebra.Inverse{LazyAlgebra.FFTs.FFTOperator{Float64,2,Complex{Float64},FFTW.rFFTWPlan{Float64,-1,false,2,UnitRange{Int64}},FFTW.rFFTWPlan{Complex{Float64},1,false,2,UnitRange{Int64}}}},LazyAlgebra.NonuniformScaling{Array{Complex{Float64},2}},LazyAlgebra.FFTs.FFTOperator{Float64,2,Complex{Float64},FFTW.rFFTWPlan{Float64,-1,false,2,UnitRange{Int64}},FFTW.rFFTWPlan{Complex{Float64},1,false,2,UnitRange{Int64}}}}}

typeof(D)=Array{Float64,3}

Where does that A come from?

from a PSF file

It would be nice, if you can provide minimal working example, so people can reproduce your problem locally and give you reasonable answer.
