Function fft_convolve2 

pub fn fft_convolve2<T, F>(
    signal: &Array<T>,
    filter: &Array<F>,
    mode: ConvMode,
) -> Array<T>
where
    T: HasAfEnum,
    F: HasAfEnum,

2d convolution using fast-fourier transform

Parameters

• signal is the input signal
• filter is the signal that shall be used for convolution operation
• mode indicates if the convolution should be expanded or not(where output size equals input). It takes values of type ConvMode

Return Values

Convolved Array
