SRAND — Reinitialize the random number generator

Description

SRAND 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.

Syntax

CALL SRAND(SEED)

Arguments

SEED Shall be a scalar INTEGER(kind=4).

Return value

Does not return anything.

Example

See RAND and IRAND for examples.

Notes

The Fortran standard specifies the intrinsic subroutines RANDOM_SEED to initialize the pseudo-random number generator and RANDOM_NUMBER to generate pseudo-random numbers. These subroutines should be used in new codes.

Please note that in GNU Fortran, 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 number generators.
