gb_emptyelem_i(3PI) Sun Interval Performance Library gb_emptyelem_i(3PI)NAMEgb_emptyelem_i - Empty entry and its location.
DESCRIPTION
K = index of empty entry or K=-1
The routine GB_EMPTYELEM_I checks if an general band interval matrix A
contains an empty interval entry. If A contains empty interval entries,
then the routine returns the smallest offset or index K (according to
the first index) such that Akj = [NaN_empty,NaN_empty]. Otherwise, the
routine returns K=-1.
