Logically Collective
Input Parameters#
A - the matrix
prefix - the prefix to prepend to all option names for the factored matrix

A hyphen (-) must NOT be given at the beginning of the prefix name. The first character of all runtime options is AUTOMATICALLY the hyphen.
Normally the prefix is automatically passed in from the PC calling the factorization. To set
it directly when not using KSP/PC use MatAppendOptionsPrefixFactor()
