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

Comments

The supported strings for the distribution type are as follows. 'beta' 'chi2' 'chisquare' 'exp' 'exponential' 'f' 'gam' 'gamma' 'logn' 'lognormal' 'norm' 'normal' 'poiss' 'poisson' 't' 'unif' 'uniform' 'wbl' 'weibull'
