Dear PDL folks, PDL 2.049 has just been released. Notable changes:
Matrix stuff: - MatrixOps::identity now preserves higher dims on multi-dim input - MatrixOps::lu_decomp now preserves inplace flag on input - MatrixOps::lu_backsub now gets output dims right including inplace - thanks @wlmb for report Complex numbers: - PDL::Complex->from_native / as_native - parse simple complex-number strings e.g. ‘[1+i 2-3i]’ - replace PDL::Complex stringification with native-complex version - PDL::r2C able to take Perl scalars - add PDL::i2C - replace creal, cimag with re, im, for easier PDL::Complex -> native transition - change default r2C and i2C input types to D from F - add czip($re, $im) -> native complex - i() as function (not constant) like nan() - ci() removed - add abs2 - pdl([native-complex]) now creates a native-complex ndarray - sumover/prodover now also process native complex - comparing PDL::Complex and native complex other than for equality now a fatal error, can == with real - PDL::Complex slices that affect 0-th dim get re-blessed as PDL - PDL::Complex can assign real values and threading won't also assign to imag - PDL::Constants only loads PDL::Complex on demand General stuff: - copy now copies ndarray and leaves original ndarray's inplace alone - SvPDLV gives more comprehensible error if given a hash without "PDL" key - Inline now not a dep but if installed gets updated to suitable version - new pdlperl.h for Perl-specific functions/macros - $PDL::undefval can be ndarray - overloading now done in PDL::Ops/Primitive where functions defined - overloading honours subclass methods As usual, please give it a try and report problems. Best regards, Ed
