How to select real positive number ?

How do I pick up only real positive numbers from array or matrix which has all types of numbers such as positive ,negative real numbers and complex numbers?

I tried A(A>0) but it returns positive number but also complex numbers whose real part is positive.

For example, A=[1,-3,4,1+2i,5-3i,-9-i,9+3i];

B=A(A>0)

then I got

B=[1,4,1+2i,5-3i,9+3i]

But how do I get B=[1,4]?

Thanks

 B=A(real(A)>0&imag(A)==0);
