normpdf

Compute normal distribution probability density function values.

Syntax

d=normpdf(x)

d=normpdf(x,mu,sigma)

Inputs

x
Values of the distribution random variable.
Type: double
Dimension: scalar | vector | matrix
mu
Mean (default = 0).
Type: double
Dimension: scalar | vector | matrix
sigma
Standard Deviation (default = 1).
Type: double
Dimension: scalar | vector | matrix

Outputs

d
Probability density values.

Examples

Single value normpdf example:

x = 4;
mu = 5;
sigma = 3;
d = normpdf(x,mu,sigma)
d = 0.12579
Vector normpdf example:
x = [1:1:7];
mu = 5;
sigma = 3;
d = normpdf(x,mu,sigma)
d = [Matrix] 1 x 7
