Maxima Function

Calling Sequence

pdf_exp (x,m)

Description

Returns the value at x of the density function of an Exponential(m) random variable, with m>0.

The Exponential(m) random variable is equivalent to the Weibull(1,1/m), therefore when Maxima has not enough information to get the result, a noun form based on the Weibull density is returned.
