Initialise the matrix-solve.
On each process an array of IDs for each global degree of freedom is supplied which corresponds to a unique numbering of universal degrees of freedom. Three vectors describing the matrix are also provided. The parallel matrix solve is then set up.
pId | Array of integers providing universal IDs for each global DOF on the process. |
pAi | Row indices of matrix entries |
pAj | Column indices of matrix entries |
pAr | Values of matrix entries |
pComm | Communication object used for inter-process communication. |
