Struct realfft::ComplexToRealOdd [−][src]
Implementations
impl<T: FftNum> ComplexToRealOdd<T>
[src]
pub fn new(length: usize, fft_planner: &mut FftPlanner<T>) -> Self
[src]
Create a new ComplexToReal FFT for input data of a given length, and uses the given FftPlanner to build the inner FFT. Panics if the length is not odd.

impl<T: FftNum> ComplexToReal<T> for ComplexToRealOdd<T>
[src]
fn process(
&self,
input: &mut [Complex<T>],
output: &mut [T]
) -> Result<(), Box<dyn Error>>
[src]
&self,
input: &mut [Complex<T>],
output: &mut [T]
) -> Result<(), Box<dyn Error>>
Transform a complex spectrum of N/2+1 (with N/2 rounded down) values and store the real result in the N long output. The input buffer is used as scratch space, so the contents of input should be considered garbage after calling. It also allocates additional scratch space as needed. An error is returned if any of the given slices has the wrong length.
fn process_with_scratch(
&self,
input: &mut [Complex<T>],
output: &mut [T],
scratch: &mut [Complex<T>]
) -> Result<(), Box<dyn Error>>
[src]
&self,
input: &mut [Complex<T>],
output: &mut [T],
scratch: &mut [Complex<T>]
) -> Result<(), Box<dyn Error>>
Transform a complex spectrum of N/2+1 (with N/2 rounded down) values and store the real result in the N long output. The input buffer is used as scratch space, so the contents of input should be considered garbage after calling. It also uses the provided scratch vector instead of allocating, which will be faster if it is called more than once. An error is returned if any of the given slices has the wrong length.
