betainc

Incomplete beta function

Syntax

• R = betainc(X, Z, W)
• R = betainc(X, Z, W, tail)

Input argument

• X - a real single or real double matrix. It must be in the closed interval [0, 1].
• Z - a real single or real double matrix. It must be nonnegative.
• W - a real single or real double matrix. It must be nonnegative.
• tail - a string 'upper' or 'lower' (default).

Output argument

• R - result of betainc function.

Description

betainc computes the Incomplete beta function.

All arrays must be the same size or any of them can be scalar.

Example

R = betainc(0.5, 1:10, 3)
