create a square wave to represent transient heat flux in a plane wall in matlab

You can use the square function in MATLAB to create a square wave signal. The square function generates a square wave with a specified frequency and duty cycle.

To represent transient heat flux in a plane wall, you can create a square wave signal with the desired frequency and duty cycle. The duty cycle will represent the time period for which a heat flux is applied to the wall.

Here's an example code to create a square wave with frequency f and duty cycle d using the square function in MATLAB:

main.m
t = linspace(0, 1, 1000); % time vector
f = 10; % frequency in Hz
d = 0.5; % duty cycle
y = square(2*pi*f*t, d*100);
plot(t, y);

In this example, t is a time vector with 1000 samples, f is the frequency of the square wave in Hz, and d is the duty cycle of the square wave as a percentage. The square function takes the frequency and time vector as inputs, and the duty cycle as an optional third argument.

The resulting square wave signal will have a period of 1/f and a duty cycle of d. You can adjust the frequency and duty cycle to create the desired transient heat flux signal for your plane wall simulation.
