Re: Random number generator

Hi Longtao,
You need to set random_setallseed if you want to have different values
generated. See the random_uniform page here:
http://www.ncl.ucar.edu/Document/Functions/Built-in/random_uniform.shtml
and the random_setallseed page here:
http://www.ncl.ucar.edu/Document/Functions/Built-in/random_setallseed.shtml
Hope that helps. If you have further questions please reply to ncl-talk.
