conv_fft {astrochron}

Convolution through Fast Fourier Transform

Description

Convolution through Fast Fourier Transform

Usage

conv_fft(x, y, index, dt)

Arguments

x

Input signal that needs to be convolved

y

Green's function; impulse response function

index

index in the impulse response function that corresponds to the deposition time

dt

time resolution for the input series

Details

Function 'conv_fft' is used by function 'bioturb'. x and y do not need to be of the same length.

Value

z Convolved output series. length(z) = length(x)
