dwt

dwt computes the Discrete Wavelet Transformation of a vector.

fft

fft computes the Fast Fourier Transformation of a complex vector.

fwt

fwt computes the Fast Wavelet Transformation of a vector. fwt computes the Fast Wavelet Transformation of a vector.

fwt2

The algorithm fwt2 is designed for 2 dimensional wavelet transformation. It mainly corresponds to dwt for the one dimensional case. If wished it works with the tensor product of one dimensional wavelet transforms.

fwtin

fwtin computes the Fast Wavelet Transformation of all circular shifts of the vector x.

fwtinshift

fwtinshift retrieves the wavelet coefficients for a given shift of the Fast Wavelet Transformation of all circular shifts (fwtin) of a vector.

invdwt

invdwt computes the inverse Discrete Wavelet Transformation of a vector.

invfft

invfft computes the Inverse Fast Fourier Transformation of a complex vector.

invfwt

invfwt computes the Fast Wavelet Transformation of a vector.

invfwt2

The algorithm invfwt2 is designed for 2 dimensional inverse wavelet transformation. The wavelet coefficients are stored in the matrix c.

invfwtin

fwtin computes the inverse Fast Wavelet Transformation of all circular shifts from ti.
