Use 'trandn' function to draw random numbers from a lognormal distribution

Hi,

Is it possible to use the function 'trandn' to draw random number from a lognormal distribution?

For example:

mu=2;

sigma=1;

upper_bound=10;

Thanks

An easy way to get random numbers from a lognormal distribution is to get random numbers from a normal distribution and then exponentiate them. So you could use trand to generate truncated normals (rn) and then form rln = exp(rn).

Hi,

Thanks for the reply, however, I am not sure that conduct a normal distribution, and exponent the results, is like conduct a lognormal distribution..
