NAME

PDL::Lvalue - declare PDL lvalue subs

CONTENTS

DESCRIPTION

Declares a subset of PDL functions so that they can be used as lvalue subs. In particular, this allows simpler constructs such as



  $a->slice(,(0)) .= 1;



instead of the clumsy



  (my $tmp = $a->slice(,(0))) .= 1;



This will only work if your perl supports lvalue subroutines (i.e. versions >= v5.6.0). Note that lvalue subroutines are currently regarded experimental.

SYNOPSIS



 use PDL::Lvalue; # automatically done with all PDL loaders



FUNCTIONS

    subs

test if routine is a known PDL lvalue sub



  print "slice is an lvalue sub" if PDL::Lvalue->subs(slice);



returns the list of PDL lvalue subs if no routine name is given, e.g.



  @lvfuncs = PDL::Lvalue->subs;



It can be used in scalar context to find out if your PDL has lvalue subs:



  print has lvalue subs if PDL::Lvalue->subs;
