Compute mean and variance of the lognormal distribution.
Arguments
mu and sigma must be of common size or one of them must be scalar
- mu is the first parameter of the lognormal distribution
- sigma is the second parameter of the lognormal distribution. sigma must be positive or zero
Return values
- m is the mean of the lognormal distribution
- v is the variance of the lognormal distribution
Examples
mu = 0:0.2:1; sigma = 0.2:0.2:1.2; [m, v] = lognstat (mu, sigma) [m, v] = lognstat (0, sigma)References
