Lappdf

Definition

$Y = lappdf(X, \mu, b)$ returns the probability density function of the Laplace distribution with location parameter mu and scale parameter b, evaluated at the values in X.

$f(x|\mu,b) = \frac{1}{2b} \exp \left( -\frac{|x-\mu|}{b} \right) \,\!$

$= \frac{1}{2b} \left\{\begin{matrix} \exp \left( -\frac{\mu-x}{b} \right) & \mbox{if }x < \mu \\[8pt] \exp \left( -\frac{x-\mu}{b} \right) & \mbox{if }x \geq \mu \end{matrix}\right.$

Parameters

x (input, double)
mu (input, double): location parameter
b (input, double): scale parameter $b >0$ .
