Module complex_fft 

Contains complex_fft::FFTErrorEstimate which provides estimates for the error when computing a complex-valued FFT using floating-point numbers.

Traits

FFTErrorEstimateunstable-enable

Trait for operations that perform float-point computations, and thus must care about precision. Currently only used for crate::algorithms::fft::FFTAlgorithm.

Functions

root_of_unity_errorunstable-enable

The absolute error in the expression exp(2 * pi * i * (x / y)).
