MATLAB: How to insert data into matrix form

Question

For example I have data in row matrix from a for loop for each element,

for i=l:3
    k11(i)
    k12(i)
    k21(i)
    k22(i)
end

I cant seem to transfer this data to 3 2×2 matrix with the relevant data. I am coding

x=1:3
k(x)=[k11(x) k12(x) etc in matrix form.

Error says

In an assignment  A(I) = B, the number of elements in B and I must be the same.

Any help? Thanks

Answer 1

Is it something like

 x = [k11, k12; k21, k22] ;

that you want to do? If knn were row vectors and you wanted to build a matrix x at some step ii of a loop, this would become

 x = [k11(ii), k12(ii); k21(ii), k22(ii)] ;
