Description: Qff2 returns the inverse of the F-distribution function with d1 and d2 degrees of freedom for the elements of an array.

Usage: y=qff2(x,d1,d2)
Input:
x input array
d1 a scalar or an array of the same dimension as x containing the number d1 of degrees of freedom for F-distribution
d2 a scalar or an array of the same dimension as x containing the number d2 of degrees of freedom for F-distribution
Output:
y output array, it contains the inverse of the specified F-distribution function for the elements of array x

Note:

Example:
