octave-nkf: liboctave/operators/mx-inlines.cc annotate

annotate liboctave/operators/mx-inlines.cc @ 18759:8cc66f091584

Add "native" option to prod() (bug #40349). * data.cc (Fprod): Rewrite docstring to mention new "native", "double" options. Borrow code from Fsum replacing sum with prod. Add %!tests for new behavior. * fCNDArray.h (dprod): New function prototype. * fCNDArray.cc (FloatComplexNDArray::dprod): New function. * fNDArray.h (dprod): New function prototype. * fNDArray.cc (FloatNDArray::dprod): New function. * intNDArray.h (prod): New function prototype. * intNDArray.cc (intNDArray<T>::prod): New function. * mx-inlines.cc (op_dble_prod): New inline functions for implementing double product.
