logn_inv — lognormal cumulative distribution
[linv]=logn_inv(x,a,v)
x = variable vector (nx1)
a = mean vector (default=1)
v = variance vector (default=1)
linv = (nxm) vector containing pdf for each x
x=logn_inv([0.1 0.5 0.9],2*ones(1,3),3*ones(1,3)) // Provide a (1x3) vector of the cumulative distribution function of a lognormal law with mean log(2) and variance 3 (for the log of the law) at values 0.1, 0.5 and 0.9. x=logn_inv([1:9]'/10) // Provides a (9x1) vector of the cumulative distribution function of a lognormal law of mean 0 and variance 1 (for the log of the law) at values 0.1, 0.2,…0.9.
