Re^2: How to call $PDL::BIGPDL=1?

Got it: when I try this:

            $name=$PDL::BIGPDL=zeroes($large_number1,$large_number2);

It works. Thank you.

For posterity; the minimum you need to do is: `$PDL::BIGPDL=1; # true value $name=zeroes($large_number1,$large_number2); # now size not checked` [download] An even better solution to the problem is to use PDL::IO::FastRaw and memory-map a disk-file, which doesn't allocate any RAM at all: `use PDL::IO::FastRaw; $name=mapfraw( 'fname', {Creat => 1, Dims => [$large_number1,$large_number2]} );` [download]	[reply] [d/l] [select]

use PDL::IO::FastRaw;
$name=mapfraw(
  'fname',
  {Creat => 1, Dims => [$large_number1,$large_number2]}
);
