Help text

 lyngby_cdf_f         - Fisher's F distribution

       function P = lyngby_cdf_f(x, r1, r2)

       Input:  x   Value where the function is evaluated
               r1  Degrees of freedom
               r2  Degrees of freedom

       Output: P   Lower tail area

       Lower tail (cumulated) Fisher's F-distribution. The value is 
       computed by calls to the incomplete beta function.
