Definition

exppdf(x,lambda) returns the probability density function of the exponential distribution with rate parameter lambda, evaluated at the values in x.

f(x|\lambda)=\lambda e^{{-x}{\lambda}}, x \geq 0

where \lambda is the rate parameter. Mean parameter, Standard Deviation parameter or scale parameter \mu = \frac {1}{\lambda}

Parameters

x (input, double)
x \geq 0
lambda (input, double)
\lambda>0.
