kstest2 - Undefined function 'kstest2' for input arguments of type 'double'.

Dear I have two vectors ("ano" and "sem") with 31132 data in each. Did data entry, but when I try to use the function kstest2 get an error:

>> H = kstest2 (ano, sem) Undefined function 'kstest2' for input arguments of type 'double'.

Had some guidance about?

Thanks,

Joao - the kstest2 function is part of the Statistics Toolbox. Do you have it installed? In the Command Window type

 ver

to see which version of MATLAB you have and which toolboxes you have. If you don't see the Statistics Toolbox, then you need to purchase it. If you do see it, then type the following in the Command Window

 which -all kstest2

to see where in the MATLAB search path this function can be found (if at all). What do you observe?

George, Thank you for the answer. I do not have the Statistics Toolbox installed. I believe that it would be interesting if the information came at begin in the explanation about the function in the respective help file.
