I am trying to do the nonparametric test on my data called ranksum or also known as Whiney-U test. I have very little data points, only as much as 13. I load the .txt files my data is in, then I define each sample file as x and y and when I put in

[p,h] =ranksum (x,y)

I get this error message

??? Undefined function or method 'statgetargs' for input arguments of type 'cell'.

Error in ==> ranksum at 56 [eid,emsg,alpha,method] = statgetargs(oknames,dflts,varargin{:});

All this stuff is another language to me... I have done this test before and it worked on another computer. Is it my file name, the data, or the different computer???...I have no idea, but I need this done tonight!

Thanks!
