tuple_randtuple_randTupleRandTupleRandtuple_rand (Operator)

tuple_randtuple_randTupleRandTupleRandtuple_rand — Return a tuple of random numbers between 0 and 1.

Signature

tuple_rand( : : Length : Rand)

Herror tuple_rand(const Hlong Length, double* Rand)

Herror T_tuple_rand(const Htuple Length, Htuple* Rand)

void TupleRand(const HTuple& Length, HTuple* Rand)

static HTuple HTuple::TupleRand(const HTuple& Length)

static void HOperatorSet.TupleRand(HTuple length, out HTuple rand)

static HTuple HTuple.TupleRand(HTuple length)

def tuple_rand(length: int) -> Sequence[float]

def tuple_rand_s(length: int) -> float

Description

tuple_randtuple_randTupleRandTupleRandtuple_rand returns a tuple of random numbers distributed uniformly in the interval [0,1). The parameter LengthLengthLengthlengthlength specifies the length of the output tuple, i.e., how many random numbers are generated.

The random numbers are generated using the C function “drand48()”. See the parameter 'seed_rand'"seed_rand""seed_rand""seed_rand""seed_rand" of set_systemset_systemSetSystemSetSystemset_system for information on the used random seed.

HDevelop In-line Operation

HDevelop provides an in-line operation for tuple_randtuple_randTupleRandTupleRandtuple_rand, which can be used in an expression in the following syntax:

Rand := rand(Length)

Execution Information

  • Multithreading type: independent (runs in parallel even with exclusive operators).
  • Multithreading scope: global (may be called from any thread).
  • Processed without parallelization.

Parameters

LengthLengthLengthlengthlength (input_control)  number → HTupleintHTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Length of tuple to generate.

RandRandRandrandrand (output_control)  number(-array) → HTupleSequence[float]HTupleHtuple (real) (double) (double) (double)

Tuple of random numbers.
