Manual Reference Pages - PDL::LVALUE (3)
PDL::Lvalue - declare PDL lvalue subs
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.
use PDL::Lvalue; # automatically done with all PDL loaders
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;
