octave: libinterp/corefcn/xpow.cc annotate

annotate libinterp/corefcn/xpow.cc @ 29816:f54cfd60725e

Fix mpower for additional cases where negative scalar base is used (bug #60786). * xpow.cc (xpow (double, ComplexMatrix), xpow (float, FloatComplexMatrix)): Check for base < 0.0 and if found use std::pow with std::complex first argument so that math library chooses a different template for function which can handle negative bases.
