MATLAB: How to create the definite cycle and to display the result of a cycle in a single matrix of a definite size

cycleMATLABmatrix manipulationoutputrepresentsparse matrix

Hello, I have cycle to represents b as matrix.
m=[];
  b=[4]; 
      for i=0:6 %Creating cycle 
          b=circshift(b,[0,i]); %Shift b 
          z=zeros(1,7,'int8'); %Create zeros string to represents b as 0 0 0...b..0
          if b==0 %If b=0 then z=1 0 0...0
              z(1)=1;
              m=[m; z];
          else
              z(b)=b; 
              b=mod(b,7); 
              b=b+1;
              m=[m; z];
          end
      end

I need to create the cycle for represent matrix b, for example, b=[1 2; 5 6] . In the form matrix m dimension 7*2×7*2=14×14. Only necessary that each value of b displayed by its matrix m For example, for b=[1 2; 3 4], I need create the following m:
m =
    1    0    0    0    0    0    0    0    2    0    0    0    0    0
    0    2    0    0    0    0    0    0    0    3    0    0    0    0

A = eye(7).*repmat(1:7,7,1);
[x,y] = size(b);
m = zeros(7*x,7*y);
for i = 1:x
  for j = 1:y
    if (b(i,j) == 0)
       m((i-1)*7+1:i*7,(j-1)*7+1:j*7) = 0;
    else
       m((i-1)*7+1:i*7,(j-1)*7+1:j*7) = circshift(A,(-1)*b(i,j)+1);
    end
  end
end
This will do it.
