Solve error : Index in position 2 exceeds array bounds. Index must not exceed 15.

a=2;

m=5;

n=15;

%ADM is matrix of size 5by15

for i=1:m

for k=1:3

B(i,k)=0;

for j=1:n/3

B(i,k)=ADM(i,3*j-a)+B(i,k);

end

a=a-1;

end

end

ADM is 5x15.

You're trying to access ADM(i,3*j-a) when j = 5 and a = -1. 3*j-a = 16.

How to resolve this depends entirely on what the code is intended to do.
