Replaceability

As a common direct solver for sparse matrices, MUMPS supports only the coordinate list (COO) storage format, which is different from KML DSS and SCADSS that support the CSR format. MUMPS provides the structure [SDCZ]MUMPS_STRUC. You can control the solution process by configuring variables in the structure, for example, JOB that specifies the operation performed by MUMPS, and arrays ICNTL and CNTL that are used to configure the MUMPS solution function. You can also obtain the intermediate or final solution result by using the structure.
