Function Documentation

s2let_allocate_f_wav()

void s2let_allocate_f_wav	(	complex double **	f_wav,
		complex double **	f_scal,
		const s2let_parameters_t *	parameters
	)

Allocates arrays for wavelet transform in wavelet space.

Parameters

[out]	f_wav	Pointer to allocated space for array of wavelet maps, using MW sampling.
[out]	f_scal	Pointer to allocated space for scaling function map, using MW sampling.
[in]	parameters	A parameters object with (at least) the following fields: B, L, J_min N

Return values

none

s2let_allocate_f_wav_manual()

void s2let_allocate_f_wav_manual	(	complex double **	f_wav,
		complex double **	f_scal,
		int *	wav_bandlimits,
		int	scal_bandlimit,
		int	N,
		int	J,
		const s2let_parameters_t *	parameters
	)

Allocates arrays for wavelet transform with manual wavelet tiling. Multiresolution is active and depends on the band-limits provided.

Parameters

[out]	f_wav	Pointer to allocated space for array of wavelet maps, using MW sampling.
[out]	f_scal	Pointer to allocated space for scaling function map, using MW sampling.
[in]	wav_bandlimits	Array of integers 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]	scal_bandlimit	Same as wav_bandlimits but only one integer: the band-limit of the scaling function.
[in]	N	Azimuthal band-limit for the directional transform
[in]	J	Number of scales in total (in wav_bandlimits) is J+1.
[in]	parameters	A parameters object containing all s2let and so3 sampling options.

Return values

none

s2let_allocate_f_wav_real()

void s2let_allocate_f_wav_real	(	double **	f_wav,
		double **	f_scal,
		const s2let_parameters_t *	parameters
	)

Allocates arrays for wavelet transform of real signal in wavelet space.

Parameters

[out]	f_wav	Pointer to allocated space for array of wavelet maps, using MW sampling.
[out]	f_scal	Pointer to allocated space for scaling function map, using MW sampling.
[in]	parameters	A parameters object with (at least) the following fields: B, L, J_min N

Return values

none

s2let_allocate_lm()

void s2let_allocate_lm	(	complex double **	flm,
		int	L
	)

Allocate spherical harmonic coefficients for a given bandlimit L.

Parameters

[out]	flm	Pointer to allocated space for spherical harmonic coefficients.
[in]	L	Angular harmonic band-limit.

Return values

none

void s2let_allocate_lmn_f_wav	(	complex double **	f_wav_lmn,
		complex double **	f_scal_lm,
		const s2let_parameters_t *	parameters
	)

Allocates arrays for directional wavelet transform in Wigner space.

Parameters

[out]	f_wav_lmn	Wigner coefficients of the wavelet contributions. Each wavelet has size (2*N-1)*L*L and there are (J-J_min+1) scales.
[out]	f_scal_lm	Spherical harmonic coefficients of the scaling contribution (L*L).
[in]	parameters	A parameters object with (at least) the following fields: B, L, J_min N

Return values

none
