NAME

       PDL::RandVar::Sobol -- Sobol subrandom sequences

VERSION

	 Current version is 1.0

SYNOPSIS

	 use PDL::RandVar::Sobol;
	 $m = new PDL::RandVar::Sobol

DESCRIPTION

       Sobol subrandom sequences are used for more uniform sampling of a domain than normal random variables can achieve.  They're described cur-
       sorily in W.H. Press's _Numerical_ _Recipes_, 2nd edition, section 7.7 (Cambridge Univ. Press), and this implementation is based on their
       description.

History

       Bugs:

       Should have a way of reproducibly seeding the initial values.  For now, you always get the same initial seed with every random variable --
       this is the Wrong way to do it.

FUNCTIONS

       new

       Construct a new Sobol subrandom variable

	 Signature: (See PDL::RandVar::new)

	 $a = new PDL::RandVar::Sobol(<size>,<opt>);

       Options:

       range
	  2xn piddle containing min and max values for each dimension.

	 $a = new PDL::RandVar::Sobol(2,{range=>pdl([$xmin,$xmax],[$ymin,$ymax])});
	 $xy = sample $a;

NAME

       pptemplate - script to generate Makefile.PL and PP file skeleton

SYNOPSIS

	       # generate Makefile.PL and mymodule.pd in CWD
	       pptemplate PDL::MyModule;

DESCRIPTION

       The pptemplate script is the easiest way to start a new module for PDL that contains PP code (see also PDL::PP). The usage is simply

	 pptemplate modulename;

       As a result pptemplate will generate a perl Makefile for the new module (Makefile.PL) that contains the minimal structure to generate a
       module from PP code and also a skeleton file for your new module.

       The file will be called mymod.pd if you called "pptemplate" as

	 pptemplate PDL::CleverAlgs::Mymod;

       I suppose you can work out the naming rule ";)". If not resort to experimentation or the source code.

       "pptemplate" will refuse to overwrite existing files of the same name to avoid accidents. Move them out of the way if you really want to
       scrap them.

   Options
       Currently there is only the "-i" option which switches "pptemplate" into the so called internal mode.  It should only be used when you are
       starting a new module within the main PDL tree that is supposed to be part of the PDL distribution and the normal PDL build process, e.g.

	  cd PDL/IO;
	  mkdir Mpthree; cd Mpthree;
	  pptemplate -i PDL::IO::Mpthree;

BUGS

       Maybe ";)".  Feedback and bug reports are welcome.
