Modifying MATLAB code according to conditions (MATLAB)

Dear,

I have this code

A = sum(matrix(decode == 1, :), 1); 
B = max(A); 
C = find( A == B ); 
D = mod(code(C)+1,2); 

I want to modify this code, in such a way it flips only the first bit not all the bits

For example we have a sequence code where the bits are (2nd, 4th , 7th and 9th bits)

In this case I want to flip only the 2nd bits.

B = max(A);
C = find( A == B , 1 );

Or

[B,C] = max(A);
