Is there a MATLAB function to apply a 1D Gabor filter to an input?

I am aware that there are some 2D Gabor filters for image analysis - I am looking for a code for it's 1D version. Continuous or discrete are both fine.

Ran in:
% Parameters
a = 1; % Amplitude
mu = 0; % Mean
sigma = 2; % Standard deviation
f = 1; % Frequency
phi = 0; % Phase offset
N = 100; % Number of points
t = linspace(-10, 10, N); % Discrete time vector
% Gabor signal
gabor_signal = a * exp(-((t - mu).^2) / (2 * sigma^2)) .* cos(2 * pi * f * (t - mu) + phi);
% Plot
figure;
stem(t, gabor_signal);
title('1D Discrete Gabor Filter');
xlabel('Time');
ylabel('Amplitude');
