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**.
