S = segment(obj,X,P)
S = segment(obj,X,P) returns an array S of integers indicating which segment of the piecewise distribution object obj contains each value of X or, alternatively, P. One of X and P must be empty (). If X is nonempty, S is determined by comparing X with the quantile boundary values defined for obj. If P is nonempty, S is determined by comparing P with the probability boundary values.
Fit Pareto tails to a t distribution at cumulative probabilities 0.1 and 0.9:
t = trnd(3,100,1); obj = paretotails(t,0.1,0.9); pvals = 0:0.2:1; s = segment(obj,,pvals) s = 1 2 2 2 2 3
