A second order tensor S its inverse is S^-1. Using matlab randi function to gen a square (NxN) matrix S with components between 0 to 9 and N=3. Calculate the determinant by randomly picking one of the ith row of the matrix. Using a loop to multiply each jth element of the selected ith row by its minor i.e, the determinant of the (N-1xN-1) matrix obtained deleting the ith row and the jth column from matrix S(i,j).If i+j is odd multiply each product by -1 use matlab function mod(x,y) with x=i+y and y=2 to determine the sign of the product.Sum all product.

S = randi([0,9],3,3)
% Random picking the row
k = randi(size(S,1));
for i =K
for j=1:size(S)
This is the part which i dont understand
#Using a loop to multiply each jth element of the selected ith row by its minor i.e, the determinant of the (N-1xN-1)
end
end
