How to create a 3D array with matrices of unequal dimentions

Hi all!

I'm a little stuck here, I have a loop:

 for i = 1:length(n) 
  (extras)
  n_input = n(i)
  tjdf = tjdfCoef(q12,q23,n_input,lambda,mu
 end

where the output tjdf is a matrix that has a larger and larger size after each iteration. Is there anyway to put all outputs into a 3D matrix, even though all outputs aren't equal dimension?

Thanks,

Ben

No, a 3D array must have the same number of rows and columns for all pages. Use a cell array instead:

tjdf = cell(1, length(n));
for i = 1:length(n) 
  (extras)
  n_input = n(i)
  tjdf{i} = tjdfCoef(q12,q23,n_input,lambda,mu)
end

Cell arrays are useful, if it is meaningful to access the elements by indices and if the elements have different sizes and/or types.

JAN! This worked amazingly... I didn't even think of using cells. Much appreciated!
