All lines except the 8th comes up as correct but line 8 comes up as incorrect and states the reason "Variable x must be of size [2 1]. It is currently of size [2 2]. Check where the variable is assigned a value."
How can i change this code to get a [2 1] matrix instead of [2 2] ?

A = [1 2 4 5 7 ; 9 2 1 4 13] ;
B = [-11 2 ; 3 -1 ; 2 0; 5 11 ; -21 1];
C = A*B ;
D = B*A ;
s = det(C) ;
t = det(D) ;
x = inv(C).*[8 -1].^t ;
