+
+    Notes
+    -----
+    The DTCWT operator applies the dual-tree complex wavelet transform
+    in forward mode and the dual-tree complex inverse wavelet transform in adjoint mode
+    from the ``dtcwt`` library.
+
+    The ``dtcwt`` library uses a Pyramid object to represent the signal in the transformed domain,
+    which is composed of:
+        - `lowpass` (coarsest scale lowpass signal);
+        - `highpasses` (complex subband coefficients for corresponding scales);
+        - `scales` (lowpass signal for corresponding scales finest to coarsest).
+
+    To make the dtcwt forward() and inverse() functions compatible with PyLops, in forward model
+    the Pyramid object is flattened out and all coefficients (high-pass and low pass coefficients)
+    are appended into one array using the `_coeff_to_array` method.
+
+    In adjoint mode, the input array is transformed back into a Pyramid object using the `_array_to_coeff`
+    method and then the inverse transform is performed.
