I have a loop that generates a new matrix with each iteration. How do I store the matrix for each iteration?

I am coding a program that allows a user to unput the values that they have for any 1D truss problem. It will then solve the problem using finite element analysis. I need to use the values that the user gives and calculate the local stiffness matrix for each element, and then I need to assemble the local matrices into a global stiffness matrix. I have been able to get my program to find the local stiffness matrix for each element, however, I cannot figure out how to store this matrix for each element. For example, I want to store these matrices as KE(i), where i denotes the local stiffness matrix for the ith element. However, my code reads this as though I am wondering what the ith value of the matrix is instead. How can I tell it to use the ith matrix, and not the ith value in the matrix?

Use a cell array:

C = cell(1,N);
for i = .. your loop
    C{i} = ..
end
