MATLAB: Sorting integers into two arrays based on positive or negative.

arrayfor loopsort

I'm having trouble sorting all the integers into the two separate arrays. I can only recall the last positive and last negative numbers in the arrays.
This is what i have so far.
H = randi([-20,20],1,16);
for array = H;  
   if array<0
      H1 = array;
   elseif array>=0
      H2 = array;  
   end   
end
H1
H2
when the program runs this is the output.
H1 =
    -3
H2 =
    14
I'm fairly new to the matlab program so any help is appreciated.

I would do it with logical indexing:
H = randi([-20,20],1,16)
H1 = H(H < 0)
H2 = H(H >= 0)
H =
     6   -14   -16     0    19    -7     3   -11    10   -10     0     8    16    19     2   -15
H1 =
   -14   -16    -7   -11   -10   -15
H2 =
     6     0    19     3    10     0     8    16    19     2
