How can I make the mean of 3d matrices in a cell in Matlab?

  I have a 1x12 cell in Matlab and each element of this cell has a 3d matrix. I want to make the mean of these 3d matrices, so that I obtain a 3d matrix that has the same dimensions of each one of the 3d matrices of the cell and that is the mean of the 12 3d matrices. How can I do this operation ? I tried to extract each cell and create a 4d matrix so that I could do  mean(fourdmatrix,4)  . However, it seems not possible to create a 4d matrix. Ideed, a code like this:   cell={threedmatrixA, threedmatrixB, ...} fourdmatrix=[]; for i=1:12 fourdmatrix(i)=cell{i}; end does not work.

One you have the data in a 4d array it's simple enough, just use mean and supply the dimension to work over as you suggest. As @Cris notes you might run out of memory forming the 4d array (since it will copy all the data) in which case you'll want to loop over the existing arrays. But if you have enough memory this should work:

 

% make 12 random 3d arrays in cell array `c`
for i=1:12
    c{i} = rand(10, 10, 10); 
end

% Make a 4d array:
array4d = cat(4, c{:}); % Same as writing cat(4, c{1}, c{2}, c{3}, etc)

What are some good alternatives to Simulink?

Depending on what you need there are plenty of Free, Libre and Open Source Software (FLOSS) available: Modelica language is the most viable alternative and in my opinion it is also a superior option to MathWorks SIMULINK. There are open source implementations  OpenModelica  and  JModelica . One of the main advantages with Modelica that you can code a multidimensional ordinary differential equation with algebraic discrete non-causal equations. With OpenModelica you may create a non-causal model right in the GUI and with
