I would like to construct a three-dimensional 3x3xL matrix from a series of one-dimensional vectors.
So far I achieve this with the following code:
St = zeros(3.0, 3.0, L);
for i = 1:L
St(:, :, i) = [Sxxi(i), Txyi(i), Txzi(i);...
Txyi(i), Syyi(i), Tyzi(i);...
Txzi(i), Tyzi(i), Szzi(i)];
Where each of the six tensor components is a vector of size 1xL. I find this code to be quite silly and unnecessarily slow.
I'm wondering if there's a way to concatenate the six components into the 3x3xL matrix without using a FOR loop? At fist glance it looks like this might be achievable with CAT() but I'm not sure how this would work.
The parameter L is arbitrary so I'm trying to develop a solution which works for any length.
Thanks in advance,
