a=[1 2 3 4 11 33]; I want to get the number in a from 4-9; a(a(a>3)<10) is right; a(a>3 && a<10) is wrong -- is there other correct way to make this ?

If you want to get only values between 3 and 10 (excluding the endpoints), the correct way would be:
a(a>3 & a<10)
(Not exactly sure what you meant by 'OK' but a(a(a>3)<10) definitely gives some unexpected results.)

Note that Alexandra used a single & operator there. This is correct when you are anding together boolean vectors. Use && only in things like a test in an if statement.
