Compute cumulative distribution function values.

Syntax

p=cdf(dist,x,a)

p=cdf(dist,x,a,b)

Inputs

dist
The distribution name.
Type: string
x
Values of the distribution random variable.
Type: double
Dimension: scalar | vector | matrix
a,b

Type: double | integer
Dimension: scalar

Outputs

p
Cumulative probability values.

Example

Vector example with normal distribution.

x = [1,2,3,4,5,6,7];
a = 5;
b = 3;
p = cdf('norm',x,a,b)
p = [Matrix] 1 x 7
