tb_cx_ifft — 2D `typed` op

• Data kinds: cimage → image

• Call: fullseye.apply(img, "tb_cx_ifft", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

*No figure: this op takes cimage as input. A Studio program starting from an image cannot reach that type — see the runnable examples below for how it is used.*

Usage

Inverse of :func:cx_fft: `ifft2(ifftshift(cx))`.

With `real=True` (default) the real part is returned as an image (the

imaginary part is numerical dust for a spectrum that came from a real image);

with `real=False` the full complex spatial field is returned (holography /

coherent imaging, where the imaginary part carries signal). A real array is

FFT'd first (module convenience), making `cx_ifft` an involution on it.

Typed bridge of the 2d op `cx_ifft into the 2-D evolution registry: the same implementation, called under the op(v, a, b) convention. This op has no tunable parameter; a and b` are unused.
