Question no-32

Answer is (a)        . An empty vector

Explanation:   x= [start: stepvalue : end]     return a vector containing value from start to end with a increment value of step value.

If start<=end, stepvalue must be +ve.If start>=end, step value is –ve.Otherwise it returns an empty vector.

In above example start=1, end =9 and stepvalue=-1 ( I,e –ve). So returns an empty vector.
