Dynamically creating and calling variables

Question

1 vote

I am trying to create variable names k1, k2, k3, etc. dynamically, and assign them to a matrix that I create in a function. I struggling with passing the created matrices out of the function localstiff. I tried using varargout to output the matices out of the function, but it didn't work. Also how would I put those then created matrices into a new function, Globalstiff and access those matricies there? I tried accessing these with varargin also with no success. Any help is great!

nom = input('Enter in the number of members >> \n');
nom = [1,nom];
L = [1, 2];
E = [60, 60];
I = [40, 20];
[ k ] =  localstiff( L, E, I, nom);
[ S ] = Globalstiff( k{i} , num);
function [ k ] = localstiff( l, e, j, N )
for i = 1:length(N)
n = N(i);
L = l(:,n);
E = e(:,n);
I = j(:,n);
k = [12 6*L -12 6*L; 6*L 4*L^2 -6*L 2*L^2; -12 -6*L 12 -6*L; 6*L 2*L^2 -6*L 4*L^2];
k = k*(E*I/L^3);
eval(sprintf('k%d = [k]', i));
end
end
function [ S ] = Globalstiff( varargin, num )

b = (num +1)*2;
S = zeros(b);
t = [1;4];
r = [1;4];
for i = 1:length(num)
    k = k{i};
    p = (i-1)*2;
    q = p;
    for j = 1:length(t)
        for g = 1:length(r)
            rk = k(i,j);
            i = i + p;
            j = j + q;
            zo = S(i,j);
            zr = rk + zo;
            S(i,j) = zr;
            i = i - p;
            j = j - q;
        end
    end
end
