Convert tuple to array

I’m trying to implement this equation: P = A’*D
but the type of:

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}

I tried to convert A like:

A = [A...]

to convert it and then transpose it, but I still have an error.

can you help me please?
