hi every1!!! another question...how to write the MATLAB code according to this flowchart. its a CSD concept. I am not getting how to write MATALB code for the condition..PLz any help vill be appreaciated..M new to MATLAB so finding it difficult.

That flow chart does not make sense to me. One of the boxes appears to be the action "Y> i = i+1" which does not make sense as an action.

hello Sir,

After checking the position of A if A(i,j)=1 then Y=Y+B will shift to right side bit wise. A=[0 0 1 -1 0 1 -1 1] and B=[0-1 0 1 1 -1 0 1] and Y=0, i=0; after the shifting i increments. and if i<=n the program ends where n is the number of bits.

I hope now u can help me. i have tried a code vch i have written just for A(i,j)==1.but getting an error. How to shift bits to the right.Double type means what?

Plz plz help me out

A= [0 1 -1 0 -1 1 -1 0];
B= [0 1 0 1 -1 0 -1 1];
i=0;
Y=0;
n=1:8;

%   Y=A.*B
% while(i==n)
    if (A(1,:)==1)
        Y=Y+B;
        C1=bitshift(Y,1)
        i=i+1;
    end
    if (A(1,:)==-1)
        Y=Y-B;
        C2=bitshift(Y,2)
        i=i+1;   
    end   
    if(A(1,:)==0)
         C3=bitshift(Y,3)
         i=i+1;
    else
        break;

      end

% %  if (i<=n)
%      break;
%  end
% end

This is what i have tried
