I am trying to do a 'paired' two sample ttest.
So basically, the command 'ttest2'.
However, this function does not specify whether the Ttest is 'paired' or 'unpaired' and I do not find anything in the 'help' which addresses this as a possible parameter to modulate the function 'ttest2'.
Because it is not addressed, I assume that the two sample ttest is unpaired; However, what I would like to know is whether or not matlab has a way of dealing with two sample, two tailed, paired ttests.
Any help would be appreciated.

Look at "help ttest". We probably ought to make that clear in the ttest2
help text as well.
