betainc

Compute incomplete beta function values.

Syntax

y=betainc(x,a,b)

Inputs

x
Values of the distribution random variable.
Type: double
Dimension: scalar | vector | matrix
a,b
Shape parameters.
Type: double
Dimension: scalar | vector | matrix

Outputs

y
The area in the tail.

Examples

Single value betainc example:
x = 0.5;
a = 5;
b = 3;
y = betainc(x,a,b)

y = 0.22656
Vector betainc example:
x = [0.1:0.1:0.9];
a = 5;
b = 3;
y = betainc(x,a,b)

y = [Matrix] 1 x 9
