Question

There are 3 matrices A,B,C:

A=[0 1;2 3]
B=[4 5;6 7]
C=[8 9;10 11]

How to create a new matrix D(2,2) so as its elements are arrays of a type

D = [{A(1,1), B(1,1), C(1,1)} {{A(1,2), B(1,2), C(1,12}; 
     {A(2,1), B(2,1), C(2,1)} {A(2,2), B(2,2), C(2,2)}]

For example: Using an operator D(1,1) gives the result

0, 4, 8

The bracket {} are only illustrative and do not represent a matlab syntax…

Answer 1

You are almost there:

D = [{[A(1,1), B(1,1), C(1,1)]} {[A(1,2), B(1,2), C(1,2)]};
     {[A(2,1), B(2,1), C(2,1)]} {[A(2,2), B(2,2), C(2,2)]}]

(you see the additional branches?)

D is now a cell array, with each cell containing a 1×3 matrix.

To access the cell array use this syntax:

D{1,1}
