[m, v] = expstat (mu) returns the mean and variance of the exponential distribution with mean parameter mu.

The size of m (mean) and v (variance) is the same size of the input argument.

A common alternative parameterization of the exponential distribution is to use the parameter $\lambda$ defined as the mean number of events in an interval as opposed to the parameter $\mu$, which is the mean wait time for an event to occur. $\lambda$ and $\mu$ are reciprocals, i.e. $\mu \; =\; 1\; /\; \lambda$.
