Converting Between Cell and Numeric Arrays

Use for loops to convert between cell and numeric formats. For example, create a cell array F.

• F{1,1} = [1 2; 3 4];
  F{1,2} = [-1 0; 0 1];
  F{2,1} = [7 8; 4 1];
  F{2,2} = [4i 3+2i; 1-8i 5];
  

Now use three for loops to copy the contents of F into a numeric array NUM.

• for k = 1:4
     for m = 1:2
        for n = 1:2
           NUM(m,n,k) = F{k}(m,n);
        end
     end
  end
  

Similarly, you must use for loops to assign each value of a numeric array to a single cell of a cell array.

• G = cell(1,16);
  for m = 1:16
     G{m} = NUM(m);
  end
