All the parameters have the similar meaning here, and the new parameter {{codeline|tfun}} is the handle to a function which accepts vector argument, which describes the problem to be inverted. This time the returned value should obey | All the parameters have the similar meaning here, and the new parameter {{codeline|tfun}} is the handle to a function which accepts vector argument, which describes the problem to be inverted.

It is convenient to have this version of the algorithm for problem where obtaining the transformation matrix is difficult to compute or affects performance (think fft). The algorithm is expected to give good results for linear functions. For not-too-complicated non-linear cases the chances are still there. | It is convenient to have this version of the algorithm for problem where obtaining the transformation matrix is difficult to compute or affects performance (think fft).
