- statistics: y = mnpdf (x, pk)
 Multinomial probability density function (PDF).
 
Arguments
 
- 
 x is vector with a single sample of a multinomial distribution with
 parameter pk or a matrix of random samples from multinomial
 distributions. In the latter case, each row of x is a sample from a
 multinomial distribution with the corresponding row of pk being its
 parameter.
 
- 
 pk is a vector with the probabilities of the categories or a matrix
 with each row containing the probabilities of a multinomial sample.
 
Return values
 
- 
 y is a vector of probabilites of the random samples x from the
 multinomial distribution with corresponding parameter pk. The parameter
 n of the multinomial distribution is the sum of the elements of each
 row of x. The length of y is the number of columns of x.
 If a row of pk does not sum to 1, then the corresponding element
 of y will beNaN.
Examples
 |  |    x = [1, 4, 2];
 pk = [0.2, 0.5, 0.3];
 y = mnpdf (x, pk);
  
   x = [1, 4, 2; 1, 0, 9];
 pk = [0.2, 0.5, 0.3; 0.1, 0.1, 0.8];
 y = mnpdf (x, pk);
