55 * This method is the second step of the remapping process. The remapping process works in three phases :
57 * - Set remapping options appropriately
58 * - The computation of remapping matrix
59 * - Apply the matrix vector multiply to obtain the result of the remapping
61 * This method performs the second step (computation of remapping matrix) which may be CPU-time consuming. This phase is also the most critical (where the most tricky algorithm) in the remapping process.
62 * Strictly speaking to perform the computation of the remapping matrix the field templates source-side and target-side is required (which is the case of MEDCouplingRemapper::prepareEx).
63 * So this method is less precise but a more user friendly way to compute a remapping matrix.
65 * \param [in] srcMesh the source mesh
66 * \param [in] targetMesh the target mesh
67 * \param [in] method A string obtained by aggregation of the spatial discretisation string representation of source field and target field. The string representation is those returned by MEDCouplingFieldDiscretization::getStringRepr.
68 * Example : "P0" is for cell discretization. "P1" is for node discretization. So "P0P1" for \a method parameter means from a source cell field (lying on \a srcMesh) to a target node field (lying on \a targetMesh).
