Note: If it is not alread known that the <A HREF="../IS/IS.html#IS">IS</A> is a permutation (if <A HREF="../IS/ISSetPermutation.html#ISSetPermutation">ISSetPermutation</A>()
or <A HREF="../IS/ISSetInfo.html#ISSetInfo">ISSetInfo</A>() has not been called), this routine will not attempt to compute
whether the index set is a permutation and will assume perm is <A HREF="../Sys/PETSC_FALSE.html#PETSC_FALSE">PETSC_FALSE</A>.
To compute the value when it is not already known, use <A HREF="../IS/ISGetInfo.html#ISGetInfo">ISGetInfo</A>() with
the compute flag set to <A HREF="../Sys/PETSC_TRUE.html#PETSC_TRUE">PETSC_TRUE</A>.
