preprocess the vector w (up to the current tolerance) |
Helper class for preprocessing the vector w:={j=1}^{i-1} {c_{i,j}}{} * u_j by, e.g., a linear transformation. Nontrivial instances of this class are needed when it comes to a discretization of PDEs with biorthogonal wavelet bases. There the vector w has to be multiplied with the Gramian <Psi,Psi>.
