# [−][src]Function arrayfire::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
