=head1 NAME

Math::GSL::Wavelet - 1-D (Real) Wavelets

=head1 SYNOPSIS

    use Math::GSL::Wavelet qw/:all/;

=cut

=head1 DESCRIPTION

=over 1

=item C<gsl_wavelet_alloc($T, $k)>

This function allocates and initializes a wavelet object of type $T, where $T
must be one of the constants below. The parameter $k selects the specific member
of the wavelet family.

=item C<gsl_wavelet_free($w)>

This function frees the wavelet object $w.

=item C<gsl_wavelet_name>

=item C<gsl_wavelet_workspace_alloc($n)>

This function allocates a workspace for the discrete wavelet transform. To
perform a one-dimensional transform on $n elements, a workspace of size $n must
be provided. For two-dimensional transforms of $n-by-$n matrices it is
sufficient to allocate a workspace of size $n, since the transform operates on
individual rows and columns.

=item C<gsl_wavelet_workspace_free($work)>

This function frees the allocated workspace work.

=item C<gsl_wavelet_transform>

=item C<gsl_wavelet_transform_forward($w, $data, $stride, $n, $work)>

This functions compute in-place forward discrete wavelet transforms of length $n
with stride $stride on the array $data. The length of the transform $n is
restricted to powers of two. For the forward transform, the elements of the
original array are replaced by the discrete wavelet transform f_i -> w_{j,k} in
a packed triangular storage layout, where j is the index of the level j = 0 ...
J-1 and k is the index of the coefficient within each level, k = 0 ... (2^j)-1.
The total number of levels is J = \log_2(n). The output data has the following
form,

=over

    (s_{-1,0}, d_{0,0}, d_{1,0}, d_{1,1}, d_{2,0}, ..., d_{j,k}, ..., d_{J-1,2^{J-1}-1})

=back

where the first element is the smoothing coefficient s_{-1,0}, followed by the
detail coefficients d_{j,k} for each level j. The backward transform inverts
these coefficients to obtain the original data. These functions return a status
of $GSL_SUCCESS upon successful completion. $GSL_EINVAL is returned if $n is not
an integer power of 2 or if insufficient workspace is provided.

=item C<gsl_wavelet_transform_inverse>

=back

This module also contains the following constants with their valid k value for
the gsl_wavelet_alloc function :

=over 1

=item $gsl_wavelet_daubechies

=item $gsl_wavelet_daubechies_centered

=back

This is the Daubechies wavelet family of maximum phase with k/2 vanishing
moments. The implemented wavelets are k=4, 6, ..., 20, with k even.

=over 1

=item $gsl_wavelet_haar

=item $gsl_wavelet_haar_centered

=back

This is the Haar wavelet. The only valid choice of k for the Haar wavelet is k=2.

=over 1

=item $gsl_wavelet_bspline

=item $gsl_wavelet_bspline_centered

=back

This is the biorthogonal B-spline wavelet family of order (i,j). The implemented
values of k = 100*i + j are 103, 105, 202, 204, 206, 208, 301, 303, 305 307,
309.
