octave: liboctave/numeric/qrp.cc annotate

annotate liboctave/numeric/qrp.cc @ 21280:ebdf74c15722

better use of templates for qrp classes * liboctave/numeric/qrp.h, liboctave/numeric/qrp.cc: New files for qrp classes generated from CmplxQRP.cc, CmplxQRP.h, dbleQRP.cc, dbleQRP.h, fCmplxQRP.cc, fCmplxQRP.h, floatQRP.cc, and floatQRP.h with classes converted to templates. * liboctave/numeric/module.mk: Update. * qr.cc, mx-defs.h: Use new classes.
