generate a triangle wave in matlab

To generate a triangle wave in MATLAB, you can use the sawtooth function with a parameter value of 0.5. The sawtooth function generates a sawtooth waveform, but setting the parameter value to 0.5 will produce a triangle waveform instead.

Here is an example MATLAB code to generate a triangle wave:

main.m
% Define the parameters
frequency = 1; % Frequency of the triangle wave in Hz
duration = 2; % Duration of the waveform in seconds
samplingRate = 44100; % Sampling rate in samples per second

% Generate the time vector
t = 0:1/samplingRate:duration-1/samplingRate;

% Generate the triangle wave
triangleWave = sawtooth(2*pi*frequency*t, 0.5);

% Plot the triangle wave
plot(t, triangleWave);
xlabel('Time (s)');
ylabel('Amplitude');
title('Triangle Waveform');

In this code, we specify the frequency, duration, and sampling rate for the waveform. We then generate a time vector t using the duration and sampling rate. Finally, we use the sawtooth function to generate the triangle wave and plot it using the plot function.

Make sure to adjust the values of the frequency, duration, and sampling rate based on your specific requirements.
