PetscBT - PETSc bitarrays

Level: advanced

PetscBTCreate(m,&bt) - creates a bit array with enough room to hold m values

PetscBTDestroy(&bt) - destroys the bit array

PetscBTMemzero(m,bt) - zeros the entire bit array (sets all values to false)

PetscBTSet(bt,index) - sets a particular entry as true

PetscBTClear(bt,index) - sets a particular entry as false

PetscBTLookup(bt,index) - returns the value

PetscBTLookupSet(bt,index) - returns the value and then sets it true

PetscBTLookupClear(bt,index) - returns the value and then sets it false

PetscBTLength(m) - returns number of bytes in array with m bits

PetscBTView(m,bt,viewer) - prints all the entries in a bit array

We do not currently check error flags on PetscBTSet(), PetscBTClear(), PetscBTLookup(),

PetcBTLookupSet(), PetscBTLength() cause error checking would cost hundreds more cycles then

the operation.
