Required Methods§

Source

fn execute( &self, input: &[Complex<T>], output: &mut [T], ) -> Result<(), ZaftError>

Executes the Complex-to-Real Inverse FFT.

The size of the input slice must be equal to self.complex_length(), and the size of the output slice must be equal to self.real_length().

§Parameters
  • input: The complex-valued, frequency-domain input array.
  • output: The mutable slice where the final real-valued time-domain result will be written.
§Errors

Returns a ZaftError if the execution fails (e.g., due to incorrect slice lengths or internal computation errors).

Source

fn real_length(&self) -> usize

Returns the length of the final real-valued output array (N).

This is the size of the time-domain vector that results from the inverse transform.

Source

fn complex_length(&self) -> usize

Returns the length of the complex-valued input array (N/2 + 1).
