MATLAB: Multiply two matrix of quaterions

MATLABmatrixmultiplicationquaterion

hello how we can multiply 2 matrix of quaterions
exemple
C =  {[1 2 3 4 ] [5 6 7 8  ]  ;             * {[1 2 3 4 ] [5 6 7 8  ]  ;              
     [8 9 10 11 ] [12 13 14 15  ]  }         [8 9 10 11 ] [12 13 14 15  ]  }
i had realised a function who multiply 2 matrix of quaterions
function a = matrice_multiplication(A, B) 
     [r1 , c1] = size(A);
  [r2 , c2] = size(B);
% % prevent unappropriate matrix size
if c1 ~= r2
    disp ('*** not able to multiply matrices ***')
end
for i = 1 : r1
    % Vary each column of matrix B
    for j = 1 : c2
        % Reset every new element of the final result
%          c=cell (r1 , c2)
        s = [0,0,0,0]
          % Vary each column of matrix A and row of matrix B
          for k = 1 : c1
              % Display every element to take into account
  %           disp(  A{i,k})
  %      disp   (  B{k,j})
  s  =plus(s, quatmultiply(A{i,k},B{k,j}))
  %            
        end
  %         % Assign the total of the appropriate element 
  %         % to the final matrix
         c{i,j} = s
  %                disp ( c{1,1})
  %           disp ( c{1,2})
  %             disp ( c{2,1})
  %               disp ( c{2,2})
   a{i,j} = c{i,j}
  % disp (a{i,j})
      end
  end
          end
when i test this function the result is f = matrice_multplication (a,b) the result is s =
     0     0     0     0
s =
   -28     4     6     8
s =
-216   104   132   136
c =
    [1x4 double]
a =
    [1x4 double]
s =
     0     0     0     0
s =
   -60    12    30    24
s =
-312   152   212   200
c =
    [1x4 double]    [1x4 double]
a =
    [1x4 double]    [1x4 double]
s =
     0     0     0     0
s =
   -92    36    22    56
s =
-472   296   292   360
c =
    [1x4 double]    [1x4 double]
    [1x4 double]              []
a =
    [1x4 double]    [1x4 double]
    [1x4 double]              []
s =
     0     0     0     0
s =
-188   108   110   136
s =
-696   472   500   552
c =
    [1x4 double]    [1x4 double]
    [1x4 double]    [1x4 double]
a =
    [1x4 double]    [1x4 double]
    [1x4 double]    [1x4 double]
f =
    [1x4 double]    [1x4 double]
    [1x4 double]    [1x4 double]
so i have a problem of display i need to my function diplay just f without displaying c s a ….

Suppress output by adding a semicolon to the end of each calculation. For example
c{i,j} = s;
instead of
c{i,j} = s
