Hi Koko Shi,

To plot the specified differential equation model in MATLAB, you'll want to define the parameters and initial conditions, solve the differential equation numerically, and then create the plot. The 'ode45' function in MATLAB is well-suited for solving ordinary differential equations and the 'plot' function is used to create the plot.

For more details, you can refer to the related documentation here:

1. https://www.mathworks.com/help/matlab/ref/ode45.html
2. https://www.mathworks.com/help/matlab/ref/plot.html

Here is an example code you can refer to for better understanding:

% Parameters
a = 1; 
b = 1; 
g = 1; 
v_e = 0;
u_e = 0;
theta = 0; 

odeFunction = @(t, v) -a*(v - v_e) + b*(0 - u_e) - g*theta; % Assuming u is 0

tspan = [0 10];
v0 = 1;

[t, v] = ode45(odeFunction, tspan, v0);

figure;
plot(t, v, 'LineWidth', 2);
xlabel('Time (t)');
ylabel('v(t)');
title('Solution of the Differential Equation');
grid on;

Please make sure to adjust the parameters and initial conditions to fit your specific model requirements.

Best regards,
