+    """Many useful operators, however, do not lend themselves to an explicit
+       matrix representation when used to solve large-scale problems. PyLops operators,
+       on the other hand, still represent a matrix and can be treated in a similar way,
+       but do not rely on the explicit creation of a dense (or sparse) matrix itself.
+       Conversely, the forward and adjoint operators are represented by small pieces of
+       codes that mimic the effect of the matrix on a vector or another matrix."""
