expstat - Exponential mean and variance

Syntax

[m,v] = expstat(mu)

Description

[m,v] = expstat(mu) returns the mean of and variance for the exponential distribution with parameters mu. mu can be a vectors, matrix, or multidimensional array. The mean of the exponential distribution is µ, and the variance is µ².

Examples

[m,v] = expstat([1 10 100 1000])
m =
      1     10     100     1000
v =
      1     100    10000   1000000
