PDL::Lvalue - declare PDL lvalue subs River stage two • 89 direct dependents • 94 total dependents

Declares a subset of PDL functions so that they can be used as lvalue subs. In particular, this allows simpler constructs such as $x->slice(',(0)') .= 1; instead of the clumsy (my $tmp = $x->slice(',(0)')) .= 1; This will only work if your perl suppo...
