Probability density function for Gaussian mixture distribution
Syntax
y = pdf(obj,X)
Description
y = pdf(obj,X) returns a vector y of
length n containing the values of the probability
density function (pdf) for the gmdistribution object obj,
evaluated at the n-by-d data
matrix X, where n is the number
of observations and d is the dimension of the data. obj is
an object created by gmdistribution or fit. y(I) is
the cdf of observation I.
Examples
Create a gmdistribution object defining a
two-component mixture of bivariate Gaussian distributions:
MU = [1 2;-3 -5];
SIGMA = cat(3,[2 0;0 .5],[1 0;0 1]);
p = ones(1,2)/2;
obj = gmdistribution(MU,SIGMA,p);
ezsurf(@(x,y)pdf(obj,[x y]),[-10 10],[-10 10])
