PDL::NDBin::Action::Sum - Action for PDL::NDBin that computes sum
This class implements an action for PDL::NDBin.
my $instance = PDL::NDBin::Action::Sum->new( N => $N, type => double, # optional );
Construct an instance for this action. Requires the number of bins $N as input. Optionally allows the type of the output piddle to be set (defaults to the type of the variable this instance is associated with, or at least long).
$instance->process( $iter );
Run the action with the given iterator $iter. This action will compute all bins during the first call and will subsequently deactivate the variable.
my $result = $instance->result;
Return the result of the computation.
