Function Reference
— Built-in Function: cat (dim, array1, array2, ..., arrayN)

Return the concatenation of N-d array objects, array1, array2, ..., arrayN along dimension dim.

          A = ones (2, 2);
          B = zeros (2, 2);
          cat (2, A, B)
           ans =
          
              1 1 0 0
              1 1 0 0

Alternatively, we can concatenate A and B along the second dimension the following way:

          [A, B].

dim can be larger than the dimensions of the N-d array objects and the result will thus have dim dimensions as the following example shows:

          cat (4, ones(2, 2), zeros (2, 2))
           ans =
          
            ans(:,:,1,1) =
          
              1 1
              1 1
          
            ans(:,:,1,2) =
              0 0
              0 0
