    """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."""
