One can write simple perl expressions to manipulate entire +numerical arrays all at once. For example, using PDL the perl variable +$a can hold a 1024x1024 floating point image, it only takes 4Mb of +memory to store it and expressions like $a=sqrt($a)+2 would manipulate +the whole image in a few seconds. + +A simple interactive shell (perldl) is provided for command line use +together with a module (PDL) for use in perl scripts. + +http://www.aao.gov.au/local/www/kgb/perldl/ |
