plot current output of a random permanent magnet stepper motor which the code randomly gednerates itself, with theoretical motor values in matlab

Assuming you have already generated the output of the stepper motor, you can use the following steps to plot the motor values as well as the theoretical values in MATLAB:

1. Create a time vector t that represents the time steps at which the motor output was generated.
2. Create a vector output that represents the motor output values.
3. Calculate the theoretical motor values based on the motor's specifications. You can use equations such as the ones provided in this article: https://www.applimotion.com/blog/theory-stepper-motors or use any other relevant equations. Store the theoretical values in a vector called theoretical.
4. Plot the output and theoretical vectors against the t vector using MATLAB's plot() function. Example code is provided below:

main.m
% Step 1: Create time vector
t = 0:0.1:10; % Replace with the appropriate time steps

% Step 2: Create motor output vector
output = [10 20 30 40 50 60 70 80 90 100]; % Replace with your generated values

% Step 3: Calculate theoretical motor values
% Replace with appropriate equations
theoretical = sin(t); 

% Step 4: Plot the values
plot(t, output, 'b-', t, theoretical, 'r--');
xlabel('Time (s)');
ylabel('Output');
legend('Motor Output', 'Theoretical Values');

The above code assumes that the motor output and theoretical values have the same number of data points as the time vector. If they don't, you'll need to modify the code accordingly.
