How do I single out elements in a vector?

If I was asked to single out the even elements in a vector say randi(100,1,100) How would I do that?

If I were to just want to know how many elements in the vector are even how would i do that?

Hints: You might look at the mod( ) or rem( ) function to determine if values are even. To determine how many are even, you could also look into the nnz( ) or sum( ) function on the results of the mod( ) or rem( ) function.
