Already done and tested. Works great. Thanks for making that happen to quickly, Ivar.

[julia-users] Re: hist on matrices
Ah, that's it. Thanks for looking into it. On another note (but in the same code neighborhood), what's the meaning of sub(H(H, :, j) in line 465 of statistics.jl? I'm confused by that first 'H', as I thought it would imply a function call. On Tuesday, April 8, 2014 1:39:05 AM UTC-4, Ivar Nesje wrote: Thanks for the report.
