Hi, I am new to J and when doing some experiments with random number generation I stumbled across the following behavior, which wasn't what I'd expect :
f=: 3 : 'y * ?0' f 3 2.91414 f 3 0.139888 f 3 0.990328 OK so far, but when I tried: f 3 3 it gives me : 0.0403801 0.0403801 (same values!) whereas I'd expect a behavior much like the one of '?'... Is this behavior normal ? Suppose I want to create a function to generate a random deviate from a distribution (normal for instance) with some parameters (mean and sd for instance) that will work in the same fashion as '?', ie it is possible to generate lots of random deviates at once using code such as : distri 100 $ x, where x would represent parameters, what is the best way to go ? Many thanks in advance! Benoît. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
