Re: [OctDev] randn() broken

[Michael C. <mic...@ua...>]

That would be serious if it were true, but I just tried it out and it looks ok 
to me, using randn from current CVS. Also try out 

hist(randn(10000,1),30,1);

Are you sure you're interpreting the plot correctly? The x axis labels are 
just the indices of the 10000 random numbers. If you're sure your 
interpretation is correct, could you attach an image of the plot you see to a 
message?
