dnorm

The normal density function

Calling Sequence

y = dnorm(x [,m,s])

Parameters

x

real vector or matrix

m

mean (default value is zeros(x)). m is a scalar or a matrix with the same size as x.

s

standard deviation (default value is ones(x)). s is a scalar or a matrix with the same size as x.

y

normal density function with mean m and standard deviation s, at the values of x :

Description

The normal density function.

y=exp(-0.5*((x-m)./s)^2)./(sqrt(2*pi).*s)

Examples

x = -5:0.1:5 ;
y = dnorm(x);
plot(x,y);
