because you have not define a variable before
See this
a=[1 2 3;4 5 6] % creating a matrix
a =
1 2 3
4 5 6
A= a(:,2); % means all rows with second column of a matrix
B = a(:,3); % means all rows with third column of matrix
[R,P] = corrcoef(A,B) %cross correlation
R = % 1 showing good correl
1 1
1 1
P = %depends upon your data set NaN means no corr
1 NaN
NaN 1
hope this will be fine.
