warp.tile_ifft#

warp.tile_ifft(
inout: Tile[Vector[Float, Literal[2]], tuple[int, int]],
) → None#

  • Kernel

  • Differentiable

Compute the inverse FFT along the second dimension of a 2D tile of data.

This function cooperatively computes the inverse FFT on a tile of data inplace, treating each row individually.

The transform is unnormalized, meaning that applying tile_fft() followed by tile_ifft() will scale the data by N, where N is the FFT size (the second dimension of the tile). Normalization is left to the user to perform as needed.

Supported datatypes are:

  • vec2f, vec2d

Parameters:

inout – The input/output tile.
