Create matrix with random binary element in matlab

Question

I want to create a matrix in matlab with 500 cell (50 row,10 column ), How I can create and initialize it by random binary digits? I want some thing like this in 50*10 scal

Answer 1

Try this:

A = rand(50, 10) > 0.5;

The decimal equivalent of the nth row is given by:

 bin2dec(num2str(A(n,:)))

or, if you prefer,

sum( A(n,:) .* 2.^(size(A,2)-1:-1:0) )   % for big endian
sum( A(n,:) .* 2.^(0:size(A,2)-1) )      % for little endian

which is several times faster than bin2dec.
