logn_cdf — lognormal cumulative distribution
[cdf]=logn_cdf(x,a,v)
x = variable vector (nx1)
a = mean vector (default=0)
v = variance vector (default=1)
cdf = (nxm) vector containing cdf for each x
1) x=logn_cdf([0.2 0.5 1.5],2*ones(1,3),3*ones(1,3)) 2) x=logn_cdf([1:5]') Example 1 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 0.2, 0.5 and 1.5. Example 2 provide a (5x1) vector of the cumulative distribution function of a lognormal law of mean 0 and variance 1 (for the log of the law) at values 1, 2, 3, 4 and 5.
