void s2let_analysis_adjoint_wav2lm_manual	(	complex double *	flm,
		const complex double *	f_wav,

		int	N
	)

Wavelet analysis adjoint from wavelet space to harmonic space for complex signals. with fully manual wavelet tiling, using multiresolution as default with the band-limits provided in input.

Parameters

[out]	flm	Spherical harmonic coefficients of the signal
[in]	f_wav	Array of wavelets maps
[in]	f_scal	Scaling function map
[in]	scal_l	Array of size L containing the \ell space tiling for the scaling fct. It is only \ell because it is assumed to be axisymmetric.
[in]	wav_lm	Array of size (J+1)*L*L containing the (\ell, space) harmonic coefs of the wavelets. They can be directional. These must make sense and define a valid invertible transform as no extra checks are performed.
[in]	scal_bandlimit	Same as wav_bandlimits but only one integer: the band-limit of the scaling function.
[in]	wav_bandlimits	Array of integers of size J+1 containing the band-limits of the wavelets. Will be used to do the multiresolution. These must make sense and define a valid invertible transform as no extra checks are performed.
[in]	J	Number of scales in total (in wav_bandlimits) is J+1.
[in]	L	Band-limit for the transform: defines the size of all awways.
[in]	spin	Spin (integer) to perform the transform
[in]	N	Azimuthal band-limit for the directional transform
