You could also try GSL Shell [1], which contains an extensive number of random number generators [2], including the Mersenne Twister. It also contains a number of statistical and other functions, lik

Hi, I have implemented a complex library for Numlua using LuaJIT. Since it might be of more general use on its own, I'm sharing it here. All feedback is welcome (especially because I'm not proficient

Hi Dirk, So my guess was right. :) <snip> No, only once if you install it to a place that is not touched by Ubuntu, like the default /usr/local/atlas. Yes, that's the point from what I gather: GCC us

Hi Dirk, It's hard to guess without details on your platform and libs, but I think this is most probably a memory alignment issue with ATLAS. Some routines in ATLAS expect 8-byte aligned arrays, whic

Thanks again for the report and the script. Unfortunately, as you noted, it relies on `package.searchpath`. My `numlua` is just an alias to `lua -lluarocks.loader -lnumlua.seeall`. :) Yes, that's st

<snip> Great, thanks! Sorry, I wasn't clear; I meant compiling luarocks still using Lua 5.1, but specifying --with-lua-include to the dir where Lua 5.2 is installed so that 5.2's lua.h is used to bui

Most of it is very nice. I had great trouble with LuaRocks and could not get LuaHelp to see the NumLua help files, so I wrote the Lua script below, which does not need LuaHelp. The following is not s

I thought of trying to patch luarocks, but found that for numlua a common-or-garden makefile is easier. ~~~~ CC = cc -O2 -fPIC -lfftw3 -lhdf5 -llapack -lblas -shared USR1 = -I/usr/include/lua5.1 -llu

That works. And so does that. Not that simple. luarocks, even luarocks 2.0.5, makes use of setfenv. Dirk

Hi Dirk, Thanks for the report! Are you copying the files according to your package.cpath and package.path? I'd probably try instead: $ sudo cp numlua.so /usr/local/lib/lua/5.1 $ sudo mkdir /usr/loca

I don't have an operator for it; you have to use ls(a, b) -- least-squares solution -- for 'a \ b'. Cheers, Luis -- Computers are useless. They can only give you answers. -- Pablo Picasso -- Luis Ca

As an aside, in Numlua I'm defining % for matrix multiplication and * for elementwise matrix multiplication (/ and ^ keep their elementwise counterparts). It'd be nice to have a` for a:transpose(),
