fftw: report error if FFTW library fails to return wisdom (bug #52244) * fftw.cc (Ffftw): Report an error if the FFTW library fails to return a valid wisdom string. Resolves a fatal error when building with the Intel MKL implementation of FFTW, which does not implement wisdom.

112b20240c87 move docstrings in C++ files out of C strings and into comments John W. Eaton <jwe@octave.org> parents: 21724 diff changeset	78 wisdom can be treated:

112b20240c87 move docstrings in C++ files out of C strings and into comments John W. Eaton <jwe@octave.org> parents: 21724 diff changeset	84 to pick a (probably sub-optimal) plan. The advantage of this method is
112b20240c87 move docstrings in C++ files out of C strings and into comments John W. Eaton <jwe@octave.org> parents: 21724 diff changeset	85 that there is little or no overhead in the generation of the plan, which
