"Index in position 2 exceeds array bounds (must not exceed 1)"

%Index in position 2 exceeds array bounds (must not exceed 1).

I keep facing this error message when I try to create a for loop array , to generate P,E,K are 4-by-1 matrix :

Any help would be greatly appreciated. This is what I currently have

%Error in untitled4 (line 46)

% L(m,t) = P(m,t)+E(m,t)-E(m,t-1)+K(m,t)-K(m,t-1);

M=4;

T=24;

L=zeros(4,25);

P=[60; 63; 65; 70];

E=[4; 6; 8; 11];

K=[16; 18; 22; 24];

for m=1:M

for t=2:T

L(m,t) = P(m,t)+E(m,t)-E(m,t-1)+K(m,t)-K(m,t-1);

end

end

figure

plot(0:24,L(1,:), 0:24,l(2,:), 0:24,L(3,:), 0:24,L(4,:))

xlabel('t')

ylabel('L m')

legend('MG1', 'MG2', 'MG3', 'MG4')

P, E and K are (4x1) arrays.

In the loop assignment

L(m,t) = P(m,t)+E(m,t)-E(m,t-1)+K(m,t)-K(m,t-1);

you treat the arrays as if they were (4x25).

This leads to the error message.

To prevent this, define P,E and K as (4x25) instead of (4x1).
