% Decrease length of computation (use of the library function dec2bin)
%
% bin_state = mBin_state( int_state, m ) converts an vector 
% of integer into a binary matrix; the i-th row is the binary 
% form of m bits for the i-th integer; 
% For example, bin_state (3,2)-->1 1
%
% Output:
% bin_state => the converted matrix
% Inputs:
% int_state => the vector of integer need to be converted
% m => the binary representation with at least m bits. 


function bin_state = mBin_state( int_state, m )
bin_state = rem(floor(int_state.*pow2(1-m:0)),2);
