Matlab functions:

1)sumOddInts will use a for loop to sum all the odd integers between two parameters called start and finish, e.g. sumOddInts(5,9) -> 21

2)sumIntSquares will use a while loop to sum the squares of the integers from 1 to finish.

3) sumOddIntSquares will use a for loop to sum the odd squares of integers from start to finish, i.e. 16 will be skipped but 25 would be added to the sum.

4 ) factorial_recurse will use recursion to compute factorial of n.

5 ) factorial_loop will use for loop to compute factorial of n
