octave: liboctave/numeric/oct-fftw.h annotate

annotate liboctave/numeric/oct-fftw.h @ 31249:de6fc38c78c6

Make Jacobian types offered by dlsode.f accessible by lsode (bug #31626). * liboctave/numeric/LSODE-opts.in: Add options "jacobian type", "lower jacobian subdiagonals", and "upper jacobian subdiagonals". * liboctave/numeric/LSODE.cc (file scope, lsode_j, LSODE::do_integrate (double)): Handle new configurable Jacobian types. * build-aux/mk-opts.pl: Don't implicitly convert to integer in condition.
