Save a series of matrices created using a for loop

L33=-r2*sin(theta2);
L34=r2*cos(theta2);
L63=rq3*sin(theta3);
L64=rq3*cos(theta3);
L66=(r3-rq3)*sin(theta3);
L67=(r3-rq3)*cos(theta3);
L= [1 0 1 0 0 0 0 0;
0 1 0 1 0 0 0 0;
0 0 0 0 1 0 0 0;
0 0 -1 0 0 1 0 0;
0 0 0 -1 0 0 1 0;
0 0 0 0 0 0 0 0;
0 0 0 0 0 -1 0 0;
0 0 0 0 0 0 1 -1]
for i=1:length(t);
%For loop will go through every single value of t and will input every value of L33, L34,L63,L64,L66 and L67 to L matrix
L(3,3)=L33(i)
L(3,4)=L34(i)
L(6,3)=L63(i)
L(6,4)=L64(i)
L(6,6)=L66(i)
L(6,7)=L67(i)
end
So that's the part of my code that I need to fix. The theta values in L33, L34, L63, L64, L66, and L67 depend of t, which is the vector: t=[0:0.1:60]. I got the code to output all the different values of the matrix L with respect to the values of t. However, everytime the loop runs, L is overran and I don't know how to save all the matrices.

for i=1:length(t);
%For loop will go through every single value of t and will input every value of L33, L34,L63,L64,L66 and L67 to L matrix
Lout(:,:,i) = L;
Lout(3,3,i) = L33(i);
Lout(3,4,i) = L34(i);
Lout(6,3,i) = L63(i);
Lout(6,4,i) = L64(i);
Lout(6,6,i) = L66(i);
Lout(6,7,i) = L67(i);
end
Now Lout will be an 8 x 8 x length(t) matrix with the third dimension reflecting changes in t.
