Execute the inverse complex DFT on in and write the result to out for in-place execution.

Parameters
plan Pointer to the DFT plan.
out Pointer to output data (time domain). May point to the same memory as in for in-place execution.
in Pointer to input data (frequency domain).
temp Temporary (scratch) buffer. If NULL, scratch buffer of size kfr_dft_get_temp_size_f**(plan) will be allocated on stack or heap.

Note

No scaling is applied. This function reads \(N\) complex values from in and writes \(N\) complex values to out, where \(N\) is the size passed to kfr_dft_create_plan_f**.
