gamcdf

Compute gamma distribution cumulative distribution function values.

Syntax

p=gamcdf(x,a,b)

Inputs

x
Values of the distribution random variable.
Type: double
Dimension: scalar | vector | matrix
a
Shape parameter.
Type: double
Dimension: scalar | vector | matrix
b
Scale parameter.
Type: double
Dimension: scalar | vector | matrix

Outputs

p
Cumulative probability values.

Examples

Single value gamcdf example:

x = 4;
a = 10;
b = 0.5;
p = gamcdf(x,a,b)
p = 0.28338
Vector gamcdf example:
x = [1:1:9];
a = 10;
b = 0.5;
p = gamcdf(x,a,b)
p = [Matrix] 1 x 9
