Hi,

I am trying to plot each j output for y1 in a seperate subplot but i keep getting "Error using plot, Vectors must be the same length"

Can someone help, ive tried everything but nothing seems to fix this.

clc; clear all; format compact;close all
% Numerical Solution
A = 2; % m2
Kc = linspace(1,5,5); % m2/min
Ti = 0.1; % min
y2(1,[1 2 3 4 5]) = 2;
y1(1,[1 2 3 4 5]) = 0;
Ntime = 1000;
DeltaT = 50/Ntime;
t(1) = 0;
y2(1,[1 2 3 4 5]) = 2;
y1(1,[1 2 3 4 5]) = 0;
for j = 1:5
for n = 1:Ntime
y2(n+1,j) = y2(n,j)-((1/A)*(Kc(j)*y2(n,j)+Kc(j)*y1(n,j)/Ti)*DeltaT);
y1(n+1,j) = y1(n,j)+y2(n,j)*DeltaT;
t(n+1,j) = t(n)+DeltaT;
end
subplot(1,5,j)
plot(t,y1)
end
