GENCLASS

Generate class frequency distribution

   M = GENCLASS(N,P)

Input
N	Number (scalar)
P	Prior probabilities

Output
M	Class frequency distribution

Description

Generates a class frequency distribution M of N (scalar) samples  over a set of classes with prior probabilities given by the vector P.  The numbers of elements in P determines the number of classes and  thereby the number of elements in M. P should be such that SUM(P) = 1.  If N is a vector with length C, then M=N is returned. This transparent  behavior is implemented to avoid tests in other routines.

Note that this is a random process, so M = GENCLASS(100,[0.5, 0.5]) may result in M = [45 55].

This routines is used in various data generation routines like  GENDATH to determine the distribution of the objects over the classes.
