octave-nkf: liboctave/array/CMatrix.cc annotate

annotate liboctave/array/CMatrix.cc @ 19511:3746b92739f7

Replace some duplicated code and count on methods implemented on base classes. * liboctave/array/CMatrix.cc, liboctave/array/CMatrix.h, liboctave/array/dMatrix.cc, liboctave/array/dMatrix.h, liboctave/array/fCMatrix.cc, liboctave/array/fCMatrix.h, liboctave/array/fMatrix.cc, liboctave/array/fMatrix.h: remove a lot of duplicate code from Matrix type classes now that these classes inherit from their NDArrays counterpart. These mostly include operator ! and =, any_element_is_nan, any_element_is_inf_or_nan, all_elements_are_real, all_integers, too_large_for_float, all, any, cumprod, cumsum, prod, sum, sumsq, and abs. In some cases these need to still appear on the Matrix definition to avoid slicing.
