I have two 2 dimensional arrays as follows: at time step 0.1 to 1.1

A = [0 0 0 1 1 1 0 0 0 1 1 0 0 0..] B = [0 0 0 0 0 1 1 1 0 0 0 1 1 0..]

One more array Diff which is the differance of A and B Diff = [0 0 0 1 1 0 -1 -1 0 1 1 -1 -1 0...]

my logic is

lwrlmt=-0.3 upperlmt = 0.3

for j=1:length(Diff)

        if (Diff(j,2)~= 0)  
            if (Diff(j-1,2)==0) && (Diff(j+1,2)~=0)     
            Tm1 = Diff(j,1);  % if here TM1 = 0.4
            end
            if (Diff(j-1,2)~=0)&& (Diff(j+1,2)==0)
            Tm2 = Diff(j,1);  %  Tm2= 0.5
            Rais_diff=(Tm2-Tm1)*1000;  %0.5-0.4=0.1
            R_temp=int2str(Rais_diff);
            Tolerance = str2double(R_temp);
            if ((lwrlmt<=Tolerance) && (Tolerance<=upperlmt))
                disp('A and B are equal');
            else
                disp('A and B are not equal');
                break;
            end
       end
end

But above logic is failing when Diff array is

[ 0 0 0 0 0 0 1 1 1 1 1 1 ..] or [ 1 1 1 1 1 1 1 0 0 0 0]

how should I proceed further?

All we see is the code, which does not do, what you want. But you forgot to mention, what you want instead.

@Namrata Biranje: please explain what you are trying to achieve, and explain the rules of what you want the code to do. Showing us broken code is not as helpful as you actually telling us in words what you want. Please also show us complete examples with inputs and outputs, so that we have something to run code on and compare against.
