Hello every one

p = kruskalwallis(X) p = kruskalwallis(X,group) p = kruskalwallis(X,group,displayopt) [p,table] = kruskalwallis(...) [p,table,stats] = kruskalwallis(...)

all these built in function that I run but I want the output is a set of values not table or single value how I can?

I am not sure what "set of values" you are looking for. The output from the call:

p = kruskalwallis(X)

is simply the p value for the hypothesis test with null hypothesis H0: The columns of X all come from the same distribution and alternative hypothesis H1: At least one column comes from a different distribution. The table and stats variables simply give you more information regarding this test.

To interpret p, choose a significance level alpha (common choices are 0.01, 0.05, 0.1) and if the p value is less than alpha you would reject the null in favor of the alternative. Otherwise you would conclude there is statistical evidence to support the null hypothesis.
