Betapdf

Definition:

bp = betapdf( x, a, b) returns the probability density function of the beta distribution with parameters \(a\) and \(b\).

\(f(B:a,b)=\frac{\Gamma (a+b)}{\Gamma (a)\Gamma (b)}B^{a-1}(1-B)^{b-1}\) \(0\leq B\leq 1;a,b>0\)

Parameters:

x (input, double)

The value of the beta variate. \(0.0 \le x \le 1.0\)

a (input, double)

The first shape parameter, \(a\), of the required beta distribution, . \(0.0<a \le 10^6\)

b(input, double)

The second shape parameter, \(b\), of the required beta distribution, . \(0.0<b \le 10^6\)

bp (output, double)

The probability.
