function lns = lnorms(means,vars,rawelems)
% lnorms (mean,vars,rawelems)
% Converts standard normal random values (rawelems) to 
% lognormals with the defined means and variances (means 
% and vars). For 1 random value you would call:
% lnorms(mean, var, randn)
% Inputting vectors makes multiple lognormals simultaneously
% Note that vars are Variances, not st. deviations
nmeans = log(means)-0.5.*log(vars./means.^2 + 1);
nvars = log(vars./means.^2 + 1);
normals = rawelems.*sqrt(nvars) + nmeans;
lns = exp(normals);
