gammainc
Compute incomplete gamma function values.
Syntax
y=gammainc(x,a)
y=gammainc(x,a,tail)
Inputs
- x
- Values of the distribution random variable.
- a
- Shape parameter.
- tail
- The tail option ('lower' or 'upper').
Outputs
- y
- The area in the tail.
Examples
Scalar example:
x = 4;
a = 10;
y = gammainc(x,a)
y = 0.0081322428
x = [1:1:9];
a = 10;
y = gammainc(x,a,'upper')
y = [Matrix] 1 x 9
