pdf

Compute probability density function values.

Syntax

p=pdf(dist,x,a)

p=pdf(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
Distribution parameters.
Type: double | integer
Dimension: scalar

Outputs

d
Probability density values.

Example

Vector example with normal distribution:

x = [1,2,3,4,5,6,7];
a = 5;
b = 3;
p = pdf('norm',x,a,b)
p = [Matrix] 1 x 7
0.05467  0.08066  0.10648  0.12579  0.13298  0.12579  0.10648
