Calling Sequence
- F = pbeta(x,a,b)
Parameters
-
x : matrix (elements between 0 and 1)
-
a,b : positive reals, parameters of the beta distribution(x,a,b can be scalar or matrix with common size)
-
F : matrix
Description
for each element of x, F=Prob(X<x) where X is a
random variable with beta density
x.^(a-1) .* (1-x).^(b-1) ./ beta(a,b)1_{0<x<1}
