Problem w/ saving different parts of a 3D matrix in separate matrices!

I am trying to save different parts of a 3D matrix into separate individual matrices (like different matrices in one single folder). I have written the following but I get the error "Subscripted assignment dimension mismatch"! I believe the problem is the LHS; so I tried different LHS's such as indv_func(:,t), indv_func(), etc. but I keep getting different errors! Could anyone help me with resolving this pls?

for j = 1:100000;
    for t = 1:time(j);
        indv_func(:,j,t) = func_status(:,j,1:time(j));
    end
end

I also get this warning about "preallocating" but I have no idea how to resolve it, so if you have any ideas about that pls let me know too (I wrote this before the for loop but I doubt if it's appropriate!):

indv_func = zeros(size(func_status,1),100000,max(time));

There are too many things which you have to check before executing the loop.

indv_func(:,j,t) = func_status(:,j,1:time(j));

You are trying to store

    _func_status(:,j,1:time(j))_

in some variable. Third dimension is 1:time(j). And at the same time, you are trying to store this in

 indv_func(:,j,t)

See, You are trying to store indv_status whose third dimension is more than 1 in the variable indv_func whose third dimension is only 1 (because you have used t in indv_func)

You can resolve your problem by using

indv_func(:,j,t) = func_status(:,j,time(j));

OR

You have to store func_status in the cell because dimension of func_status is changing after every loop.

indv_func{j} = func_status(:,j,1:time(j));

Please attach your complete prog, if the error is still there.
