 lyngby_ts_ftest	- F-test for two samples.

       LYNGBY_TS_FTEST(X1, X2) gives the probability that the F value
       calculated as the rati of the variances of the two samples is
       greater than observed, i.e. the significance level.
       [P, F] = LYNGBY_TS_FTEST(X1, X2) gives the probability P and returns
       the value of F.

       A small value of P would lead to reject the hypothesis that
       both data sets are sampled from distributions with the same
       variances.
