Syntax

y = betainc(x, a, b)

Description

Computes the incomplete beta function of the input elements.

Details

Examples

Inputs

Name	Description
x	Specifies a matrix or a scalar number. All elements in x must have values between 0 and 1, inclusive.
a	Specifies a matrix or a scalar number. If x is a matrix, a is a matrix of the same size as x.
b	Specifies a matrix or a scalar number. If x is a matrix, b is a matrix of the same size as x.

Outputs

Name	Description
y	Returns the incomplete beta function. y is a matrix of the same size as x, a, and b.

Details

When the input elements are scalar, LabVIEW computes beta(x, a, b) using the following equation: y = (1/beta(a, b))*integral((t^(a-1))*((1-t)^(b-1)), t, 0, x).

Examples

X = 0:0.01:0.9;
A = 0.5;
B = 0.7;
Y = betainc(X, A, B);
plot(X, Y)
