pdfexp¶
Purpose¶
Computes the probability density function for the exponential distribution.
Format¶
-
p =
pdfexp(x, a, b)¶ - Parameters:
x (NxK matrix, Nx1 vector or scalar) – x must be greater than a.
a (NxK matrix, Nx1 vector or scalar) – Location parameter. ExE conformable with x.
b (scalar) – the scale parameter. sometimes called beta. b must be greater than 0.
- Returns:
p (NxK matrix, Nx1 vector or scalar) – the probability density function for the exponential distribution for the elements in x.
Remarks¶
pdfExp() calculates the probability density function for the two-parameter
exponential distribution, which is defined as
\[f(x) = \frac{1}{b} exp \big( − \frac{x−a}{b} \big)\]
