Syntax

c = gammainc(a, b)

Computes the incomplete gamma function of corresponding elements of two matrices. gammainc generalizes the gamma function.

Name	Description
a	Specifies a real matrix.
b	Specifies a real matrix. b is the same size as a unless a or b is a scalar.

Name	Description
c	Returns the incomplete gamma function of corresponding elements in a and b. c is a matrix of the same size as a or b.

When a and b are scalar, LabVIEW computes gammainc(a, b) using the following equation: c = 1/gamma(b)*integral(t^(b-1)*exp(-t), t, 0, a).

A = [0.4, 1.3, 2.5, 3.7]
B = [0.4, 1.3, 2.5, 3.7]
C = gammainc(A, B)
