I have a problem with this, I dont know whats wrong
n=4;
r= 0.012;
pos = [0 0; 0 0.5; 0.5 0.5; 0.5 0]
a = zeros(1,n)
i=1
while( i<=n)
for(j=1:1:n-1)
for(k=1:1:n-1)
x = pos(k+1,1)-pos(1,j) %%------> I have the problem here
It says "Index in position 2 exceeds array bounds"

You size of pos is 4x2....you are trying to accessing third coulmn from pos....where as it has only two columns..so obviously you will end up with error.

Since n = 4, for(j=1:1:n-1) will make j from 1 to 3.
However pos is 4x2 matrix. When j is 3, pos(1,j) refers outside of the matrix boundary.
