Re: randn newbie question

[Paul Laub]

Hamish, 

Obviously something is wrong. 

The same command on Octave 2.1.57 for Cygwin / Windows
produces a plot that looks like the Matlab one. 

Have you looked at the numbers directly? Have you
computed the mean, variance, and higher moments of
randn() output to see if they are close to theoretical
values? (That way gnuplot could be ruled out as the
source of the problem.) What does rand() output look
like? Broken too? What randn() algorithm do you use?
>> help randn   should be informative. 

Without more detail, there is not much anyone can do to
address the problem.
