MATLAB: P-value returned by non-paraemtric test

non-parametric testp-value

When you perform two-sample test with non-parametric tests such as K-S test and Mann–Whitney U test in MATLAB, is the p-value returned for a one-tailed test or for a two-tailed test?
Thanks.

Type "help kstest" and you may see (if your MATLAB is recent enough) that there's a 'Type' option to control whether it's one-tailed or two-tailed. But the default is two-tailed.
Same idea for the ranksum function.
