- I0 Int32
-
(input) INTEGER
First index.
- N0 Int32
-
(input) INTEGER
Last index.
- Z Double
-
(input) DOUBLE PRECISION array, dimension ( 4*N )
Z holds the qd array. EMIN is stored in Z(4*N0) to avoid
an extra argument.
- offset_z Int32
-
- PP Int32
-
(input) INTEGER
PP=0 for ping, PP=1 for pong.
- TAU Double
-
(input) DOUBLE PRECISION
This is the shift.
- DMIN Double
-
(output) DOUBLE PRECISION
Minimum value of d.
- DMIN1 Double
-
(output) DOUBLE PRECISION
Minimum value of d, excluding D( N0 ).
- DMIN2 Double
-
(output) DOUBLE PRECISION
Minimum value of d, excluding D( N0 ) and D( N0-1 ).
- DN Double
-
(output) DOUBLE PRECISION
d(N0), the last value of d.
- DNM1 Double
-
(output) DOUBLE PRECISION
d(N0-1).
- DNM2 Double
-
(output) DOUBLE PRECISION
d(N0-2).
- IEEE Boolean
-
(input) LOGICAL
Flag for IEEE or non IEEE arithmetic.
