function x = person_d(in)

% PERSON_DATA .... Age, height, weight profile generation.
%
%     X = PERSON_DATA(N) generates records of N persons between the ages of
%		20 to 50.  Each record contains the age, the height (in cm),
%		and the weight (in kg) of one person stored in one row of the
%		output matrix X.  The first column of X stores the age, the
%		second column stores the height, and the third column stores
%		the height.
