Hi,

I am using PDL to do an element-wise string comparison (for huge strings). As has been suggested elsewhere I am doing the following: 

use PDL; 
use PDL::Char;                                                        
+          
$PDL::SHARE=$PDL::SHARE; # keep stray warning quiet 

my $source=PDL::Char->new("ATTCCGGG");                                
+          
for my $str ( "ATTGCGGG", "ATACCGGC") {                               
+          
  my $match=PDL::Char->new($str);                                     
+         
  my @diff=($match!=$source)->list;                                   
+     
  print "@diff\n";                                                    
+          
}

I would like @diff, however, to be a piddle itself, i.e. a binary vector. Later I would like to do some operations on this binary vector and being it a piddle would make things much easier.

How can this be done? Thanks, Hadassa
