| Y | - input basis vectors | |
| M | - number of moments | |
| L | - block size | |
| L_max | - maximum block size | |
| w | - quadrature weights | |
| zn | - normalized quadrature points | |
| scat | - (optional) VecScatter object to communicate between subcommunicators | |
| subcomm | - subcommunicator layout | |
| npoints | - number of points to process by the subcommunicator | |
| useconj | - whether conjugate points can be used or not |
| S | - output basis vectors |
When using subcommunicators, Y is stored in the subcommunicators for a subset of integration points. In that case, the computation is done in the subcomm and then scattered to the whole communicator in S using the VecScatter scat. The value npoints is the number of points to be processed in this subcomm and the flag useconj indicates whether symmetric points can be reused.
