Hello Experts,

I have the following function:

function X = STK(U, D, n, delta_t)
X = zeros(1,n); % Creating the vector of X
X(1) = 1; % = X(0) = 1; 
r = randn(1,n); %
N = zeros(1);
for i=1:n
    X(i+1) = X(i) - U*X(i)*delta_t + D*sqrt(delta_t)*r(i);
    N(i) = i;
end
plot(N,X(1:n));
end

The function outputs the whole vector, I need it to output only the plot without any other ans = ... Please teach me how to do it, I mean to "enable/disable" output printing.

Happy New Year, Thanks a lot in advance!!!

在 MATLAB Online 中打开

function STK(U, D, n, delta_t)
X = zeros(1,n); % Creating the vector of X
X(1) = 1; % = X(0) = 1; 
r = randn(1,n); %
N = zeros(1);
for i=1:n
    X(i+1) = X(i) - U*X(i)*delta_t + D*sqrt(delta_t)*r(i);
    N(i) = i;
end
plot(N,X(1:n));
end
