Function summary

• configure(**kwargs)
• updateDictWithVars(adict, module, pattern, group = None)

Functions

• configure(**kwargs)

  Valid keyword arguments with defaults (other ignored):

  assumeSortedIndices = False

  Umfpack requires a CSR/CSC matrix to have sorted column/row indices. If sure that the matrix fulfills this, pass assumeSortedIndices = True to gain some speed.
