Two-sample *F*-test for equal variances

returns
a test decision for the null hypothesis that the data in vectors `h`

= vartest2(`x`

,`y`

)`x`

and `y`

comes
from normal distributions with the same variance, using the two-sample *F*-test.
The alternative hypothesis is that they come from normal distributions
with different variances. The result `h`

is `1`

if
the test rejects the null hypothesis at the 5% significance level,
and `0`

otherwise.

additional options specified by one or more name-value pair arguments.
For example, you can change the significance level or conduct a one-sided
test.
