annotate liboctave/numeric/lo-mappers.h @ 22117:9b832e9caae6

define forwarding functions for octave_int<T> xmin and xmax (bug #48139) * lo-mappers.h (min, max): Define forwarding functions for octave_int<T> types. * MArray.cc (MArray<T>::idx_min, MArray<T>::idx_max): Use octave::math::min and max as template parameters instead of xmin and xmax.
