cr.sparse.lop.dwt¶
- cr.sparse.lop.dwt(n, wavelet='haar', level=1, axis=0, basis=False)[source]¶
Returns a 1D Discrete Wavelet Transform operator
- Parameters
n (int) – Dimension of the input signal and output coefficients
wavelet (string) – Name of the discrete wavelet to be used
level (int) – Number of wavelet decompositions (default 1)
axis (int) – For multi-dimensional array input, the axis along which the linear operator will be applied
basis (bool) – If False, the transform operator is returned. If True, the wavelet basis operator is returned instead. Default False.
- Returns
A linear operator wrapping 1D DWT transform or basis
- Return type
