how to change the bit of any matrix?

A=[12 32 ;23 14];

>> D=A(:)';

>> S=de2bi(D);

>> S=de2bi(D)

S =

0 0 1 1 0 0

1 1 1 0 1 0

0 0 0 0 0 1

0 1 1 1 0 0

>> i want to make its 4th bit zero.. so what will i do?

Answer 1

[Jan]

 A = [12, 23, 32, 14];
 B = bitset(A, 4, 0)

Or:

 S       = de2bi(A);
 S(:, 4) = 0;

Answer 2

[Shameer Parmar]

try with this..

S(:,4) = 0
