make a square wave to represent cyclic heat flux generation in matlab

To make a square wave in MATLAB, we can use the built-in square function.

Here is an example code to generate a square wave with a given frequency and duty cycle to represent cyclic heat flux generation:

main.m
% define the parameters
T = 1; % period of the square wave
f = 1/T; % frequency of the square wave
duty_cycle = 0.5; % duty cycle of the square wave (50%)

% generate the square wave
t = linspace(0, 2*T, 1000); % time vector
y = square(2*pi*f*t, duty_cycle*100);

% plot the square wave
plot(t, y);
ylim([-1.5, 1.5]);
xlabel('Time (s)');
ylabel('Amplitude');
title(['Square Wave, f = ', num2str(f), 'Hz, Duty Cycle = ', num2str(duty_cycle*100), '%']);

The square function takes two arguments: the first argument is the phase of the square wave in radians, and the second argument is the duty cycle as a percentage. We set the phase to 2*pi*f*t to generate a square wave with the given frequency f and a time vector t evenly spaced within two periods of the wave. The resulting square wave is stored in the y vector, and we can plot it using the plot function.

This should generate a square wave to represent cyclic heat flux generation in MATLAB.
