Plot one Variable over another

clear variables; close all; clc;

phi_dot   = 60 
aileron   = (phi_dot)*0.5;
damp      = (100 - aileron)/100;

servo_r   =  aileron*damp;
servo_l   = -aileron*damp; 

fplot(servo_l,phi_dot[0,90])

I'm trying to plot the value of "servo_l" for each value of "phi_dot" between 0 and 90.

How should I structure my syntax?

Thanks!

Just to clarify, I've set phi_dot = 60 as a test number, it bears no real significance.

hI @Keith Blackstock,

I understand you are trying to plot the value of servo_l for each value of phi_dot between 0 and 90. MATLAB's vectorized operations and the "plot' function might be helpful for the same.

Below is the revised code showing how to achieve the same:

clear variables; close all; clc;

% Define the range for phi_dot
phi_dot = 0:1:90; % Create a vector from 0 to 90 with step size 1

% Calculate aileron, damp, and servo_l for each phi_dot
aileron = phi_dot * 0.5;
damp = (100 - aileron) / 100;
servo_l = -aileron .* damp; % Element-wise multiplication

% Plot servo_l against phi_dot
plot(phi_dot, servo_l, 'b-', 'LineWidth', 2);
xlabel('\phi_{dot} (degrees/s)');
ylabel('Servo L');
title('Servo L vs \phi_{dot}');
grid on;

For better understanding of "plot" function, refer to the following documentation:

Hope this helps!
