SRAND
— Reinitialize the random number generatorSRAND
reinitializes the pseudo-random number generator
called by RAND
and IRAND
. The new seed used by the
generator is specified by the required argument SEED.
CALL SRAND(SEED)
SEED | shall be a scalar INTEGER(kind=4) .

RAND
and IRAND
for examples.
RANDOM_SEED
to
initialize the pseudo-random numbers generator and RANDOM_NUMBER
to generate pseudo-random numbers. Please note that in
gfortran, these two sets of intrinsics (RAND
,
IRAND
and SRAND
on the one hand, RANDOM_NUMBER
and
RANDOM_SEED
on the other hand) access two independent
pseudo-random numbers generators.
