I am writing a code where i used melcepsta function and it worked fine for the first time. Later I closed Matlab completely and opened it 3 days later to run the same program, but it did not run and it gave me this error.. "Undefined function 'Melcepsta'". Before running the program after 3 days it asked whether to change the path of the .m file or add to the path.. I selected add to the path.. I have attached the .m and .fig file along. Please, any help will be appreciated.

Add the path where your missing function is to your Matlab working path. Read more here.

在 MATLAB Online 中打开

J = 0.02;
b = 0.1;
K = 0.01;
R = 1.1;
L = 0.5;
numerator = K;
denominator = [J, b, K^2];
M = tf(numerator, denominator);
T = feedback(M, 1);
C = 1/s;
one_minus_T = 1 - T;
E_ss = limit(s * C * one_minus_T, s, 0)
