# gaussianFilter

Filter signals using a frequency domain Gaussian filter

## Syntax

    signal = gaussianFilter(signal, Fs, freq, bandwidth)
    signal = gaussianFilter(signal, Fs, freq, bandwidth, plot_filter)

## Description

`gaussianFilter` applies a frequency domain Gaussian filter with the specified center frequency and percentage bandwidth to the input signal. If the input signal is given as a matrix, the filter is applied to each matrix row.

## Inputs

`signal` | signal/s to filter
`Fs` | sampling frequency [Hz]
`freq` | filter center frequency [Hz]
`bandwidth` | filter bandwidth [%]

## Optional Inputs

`plot_filters` | boolean controlling whether the filtering process is plotted

## Outputs

`signal` | filtered signal/s
