extern "C" { … }

Execute inverse real DFT on in and write the result to out.

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

Note

This function reads \(\frac{N}{2}\) (Perm format) or \(\frac{N}{2}+1\) (CCs format) complex values from in and writes \(N\) real values to out, where \(N\) is the size passed to kfr_dft_real_create_plan_f**.
