Hello, I am asking for help with plotting 3 outputs of function as Ys with input as X.

My algorithm for the function is

function [u,v,w]= g5(t)

A=[6 9 15

-5 -10 -21

2 5 11];

S=[1;2;3];

for f=t

U=expm(A*f)*S;

end

U

I want input to be I=0:0.01:1.

Thanks :)

What are u, v, w to be?

This would be my approach:

function U = g5(t)
A=[6 9 15
-5 -10 -21
2 5 11];
S=[1;2;3];
for f=1:length(t);
    ti = t(f);
    U(:,f)=expm(A*ti)*S;
end
end

Then in your calling script:

I=0:0.01:1;
U = g5(I);
figure(1)
plot(I, U)
grid

I didn’t include ‘v’ and ‘w’ in the output arguments because you didn’t define them in your code. Add them when you do.
