Function convolve2 

pub fn convolve2<T, F>(
    signal: &Array<T>,
    filter: &Array<F>,
    mode: ConvMode,
    domain: ConvDomain,
) -> Array<T>
where
    T: HasAfEnum,
    F: HasAfEnum,

2d convolution

Parameters

• signal is the input signal
• filter is the signal that shall be flipped for convolution operation
• mode indicates if the convolution should be expanded or not(where output size equals input). It takes a value of type ConvMode
• domain indicates if the convolution should be performed in frequencey or spatial domain. It takes a value of type ConvDomain

Return Values

Convolved Array
