## 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)
