Finding the p-value using MatLab

I'm trying to use MatLab to compute p-values for
different sets of data that i "play" with. However,
i seem to have big time trouble finding the right
tools for that. Any suggestions?

I've asked on a MatLab-group before but there
were rather few replies (as in zero). I was hoping
somebody here had some hints.

Let's say i have the following:
val = cdf ('chi2', spot, 99)
which allows me to simply check what cdf we have
accumulated in the point of spot.

Now, i wish to go the other way around and given the value
of val, get the corresponding value of spot.

As we're at it - is there a nice way of obtaining the
confidence interval (provided the data above)?
