gsl_wavelet.h declares functions gsl_wavelet2d_transform_forward,
gsl_wavelet2d_transform_inverse, gsl_wavelet2d_nstransform_forward, and
gsl_wavelet2d_nstransform_inverse. These functions are also documented in the
manual (pp. 309, 310). However, no implementations are given in dwt.c.
Granted these functions are trivial as they should simply set the
gsl_wavelet_direction argument in the call to the base functions, they still
managed to go AWOL in two versions already. Note that test.c does not test
those functions either.
As a general note, it's all too easy to have a missing function, since a
declaration without implementation does not usually generate an error. I
already reported missing GSL functions in the past; my way of finding those is
to compile a windows dll using a def file. I dump all functions declared in
include files into a def file; any unimplemented function will generate an
error at this point (at least, that's how it works in MSVC).
