Andres:

Anthony is correct; the trirand description is wrong.

It should read (according to Dodge and Jerse, p.271):
trirand -- Triangular distribution random number generator

Also, the following corrections should be made to the examples (for the 
opcodes) below:

For betarand, bexprnd, trirand, unirand and weibull
the final sentence should read:
Its output should include *a line* like.....

For betarand and trirand
the output should be between 0 and 1.

For bexprnd
the output should be between -1 and +1

I was wondering the other day whether this statement about trirand is
correct or not:

"trirand < Linear distribution random number generator."

I think it would be great if the various noise opcodes gave at least a short
description of how they differ from each other (i.e. describe the
distributions).  I don't have access to the Dodge/Jerse or Roads books to
look up the citations.

Hi Art and Anthony,

Thanks for the corrections, I've integrated them.

I think trirand and bexprand should output values from -krange to
+krange, or am I wrong?

Cheers,
Andrés
