NAMEPDL::Delta - PDL changes between V1.0 and V2.0DESCRIPTIONThis file is an attempt to list the major user-visible changes between PDL versions 1.0 and 2.0.Core ChangesPiddles are not hashes any more:$a = zeroes 10,10; $$a{FOO} = "bar" doesn't work. They are currently scalar references (to opaque C structures in finer terms) because of speed as well as syntactic issues. If you want to have a hash, use $a->hdr() which returns a reference to an anonymous hash. Also, subclassing works if you store a piddle in the hash member ``PDL''. There are also many core enhancements to support Dataflow and Slicing tricks, but these do not introduce any incompatibilities. Incompatible Changes vs 1.11
Documentation ChangesMany of the base and library pods were updated.SEE ALSOThe Changes file for exhaustive details on what changed.The INSTALL file for how to build PDL. The README file for general stuff. HISTORYpdldelta was inspired by perldelta man page in the Perl 5.004 distribution.
