how to find max value on matrix and mark it

A = [1 2 3; 2 4 2; 6 4 3] if A is a matrix, how to find max value on A and mark the max value with 1? the output would be like = [0 0 0; 0 0 0; 1 0 0]. does anyone know how to do that? thanks in advance.

A = [1,2,3;2,4,2;6,4,3];
B = A==max(A(:))

B = 3×3 logical array
   0   0   0
   0   0   0
   1   0   0
