- statistics: [m, v] = lognstat (mu, sigma)
Compute mean and variance of the lognormal distribution.
Arguments
-
mu is the first parameter of the lognormal distribution
-
sigma is the second parameter of the lognormal distribution.
sigma must be positive or zero
mu and sigma must be of common size or one of them must be
scalar
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)
