in reply to Access element of a piddle

There are probably people here who can give a better answer than me. There are *certainly* people on the PDL mailing list who can provide a better answer than I can.

As a quick stab, you could try at():
pdl> help at Module PDL::Core at Returns a single value inside a piddle as perl scalar. $z = at($piddle, @position); $z=$piddle->at(@position); @position is a coordinate list, of size equal to the number of dimensions in the piddle. Occasionally useful in a general context +, quite useful too inside PDL internals. pdl> $x = sequence 3,4 pdl> p $x->at(1,2) 7 at converts any bad values into the string 'BAD'. # line 3108 "Basic/Core/Core.pm.PL (i.e. PDL::Core.pm)" pdl>
but I don't know if that's the best option.

Cheers,
Rob
