Function Documentation

s2let_transform_axisym_allocate_hpx_f_wav_real()

void s2let_transform_axisym_allocate_hpx_f_wav_real	(	double **	f_wav,
		double **	f_scal,
		int	nside,
		const s2let_parameters_t *	parameters
	)

Allocates arrays for wavelets and scaling functions in pixel space (Healpix sampling).

Parameters

[out]	f_wav	Array of wavelets HEALPIX maps.
[out]	f_scal	Scaling function HEALPIX map.
[in]	nside	HEALPIX resolution parameter.
[in]	B	Wavelet parameter.
[in]	L	Angular harmonic band-limit.
[in]	J_min	First wavelet scale to be used.

Return values

none

s2let_transform_axisym_wav_analysis_hpx_real()

void s2let_transform_axisym_wav_analysis_hpx_real	(	double *	f_wav,
		double *	f_scal,
		const double *	f,
		int	nside,
		const s2let_parameters_t *	parameters
	)

Perform wavelet transform in real space (from scratch, gives wavelet maps). Input function is real. Sampling scheme : HEALPIX sampling. Spherical wavelets : analysis in real space, HEALPIX sampling. Note : multiresolution in used in harmonic space but all maps are at resolution nside.

Parameters

[out]	f_wav	Array of wavelets HEALPIX maps.
[out]	f_scal	Scaling function HEALPIX map.
[in]	f	Input function (HEALPIX map)
[in]	nside	HEALPIX resolution parameter.
[in]	B	Wavelet parameter.
[in]	L	Angular harmonic band-limit.
[in]	J_min	First wavelet scale to be used.

Return values

none

		int	nside,
		const s2let_parameters_t *	parameters
	)
