ProbDist1D

PROBDIST1D
   Usage: [P bins] = ProbDist1D(x, nbins);

 This function calculates the discrete probability distribution for a
 variable that is in a one dimensional phase space.  It is simply a
 normalized histogram using 'hist', so nbins can take any form that hist
 can take, although it does not allow for all the other hist options.
