Hi,

adtest(x,'distribution','ev')

x - Sample Data

Other two arguments are name value pair where 'ev' represents Extreme Value Distribution. Refer this documentation for more information.

You cannot test for binomial distribution using anderson darling test. Alternatives can be Chi-Square goodness-of-fit Test. Refer these links to get more information
