FMS Factoring Parameter PIVMIN
Data Type
REAL*8
Default Value
0.0D0
DESCRIPTION:
When performing matrix factoring, if FMS detects a pivot value less than or equal to PIVMIN, a zero pivot condition results. For complex data, the square of the pivot is compared to PIVMIN.
The action taken when a zero pivot condition occurs is controlled by the FMS parameter
MZERO.
A zero pivot condition can also result if FMS detects that a significant number of bits were lost in computing the pivot, as specified by
NBITSZ.
