The inverse real FFT functions in FFTW destroy the input arrays during the calculation, i.e. the irfft family of functions in xtensor-fftw. (In fact, this does not always happen, depending on which algorithm FFTW decides is most efficient in your particular situation. Don't count on it,...
Most filters can’t simply block all sine waves above or below a particular frequency. Instead, a sine wave with a particular frequency is attenuated based on its distance from the cutoff or center frequency with a roll-off effect. The slope of this roll-off is governed by a property of ...

Derivative f’ of function f(x)=arctan x is: f’(x) = 1 / (1 + x²) for all x real. To show this result, we use derivative of the inverse function tan x.
Small-angle scattering (SAS) is a technique that is able to probe the structural organization of matter and quantify its response to changes in external conditions. X-ray and neutron scattering profiles measured from bulk materials or materials deposited
Assuming sphericity of the bubble, the projection inversion is given by the inverse Abel transformation. We use a regularized version of the inverse Abel transform, which stabilizes the inner voxels with low volumetric weight against noise (see “Methods”), to obtain the 3d phase shift ϕ(R)...
