plot symmetrical triangle wave with controlled period peak at 1 and minimum peak -1 in matlab

To plot a symmetrical triangle wave with controlled period, peak at 1, and minimum peak at -1 in MATLAB, you can use the following code:

main.m
% Define the parameters
period = 2;             % Period of the wave
amplitude = 1;          % Amplitude of the wave

% Calculate the number of points for one period
points_per_period = 100;        % Adjust this value to control the smoothness
num_points = round(points_per_period * period);

% Generate the time vector
t = linspace(0, period, num_points);

% Generate the triangle wave
triangle_wave = amplitude * sawtooth(2*pi*t/period, 0.5);

% Plot the triangle wave
plot(t, triangle_wave);

Explanation:

• We first define the parameters such as the period and amplitude of the triangle wave.
• Then, we calculate the number of points needed for generating one period of the waveform. The points_per_period variable controls the smoothness of the waveform.
• Next, we generate a time vector t using the linspace function, ranging from 0 to period, with num_points equally spaced points.
• Finally, we use the sawtooth function with a duty cycle of 0.5 to generate the symmetrical triangle wave. We multiply it by the amplitude to adjust the peak values. Then, we plot the waveform using the plot function, and add appropriate labels.

You can adjust the period and amplitude variables to achieve the desired wave properties.
