How do you do planned comparison in Matlab

I searched, it seems there is no function for this.

[Fangjun Jiang]

No idea what are you talking about.

No function for what?!

[Walter Roberson]

Do an infinite number of _unplanned_ comparisons and reject them all. Whatever is left over must be a planned comparison.

@Walter: Is "all" well defined when talking about a set of infinite size?

@Yuqi: If you mean something like this http://www.psychwiki.com/wiki/What_is_a_planned_comparison%3F take the time to explain it explicitely.

I see, thanks!
