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)
