Build IJ Matrix of the sparse approximate inverse (factor)
Build IJ Matrix of the sparse approximate inverse (factor). This function explicitly creates the IJ Matrix corresponding to the sparse approximate inverse or the inverse factor. Example: HYPRE_IJMatrix ij_A; HYPRE_ParaSailsBuildIJMatrix(solver, \ij_A);
- Parameters:
- solver - [IN] Preconditioner object.
pij_A - [OUT] Pointer to the IJ Matrix.alphabetic index hierarchy of classes
