Function Documentation

ytRandom_dSFMT_new_init()

ytRNG_dSFMT * ytRandom_dSFMT_new_init

(

uint32_t

seed

)

Generates an instance for dSFMT random number generator.

Parameters

seed

ytRNG_dSFMT_close_open()

double ytRNG_dSFMT_close_open

(

ytRNG_dSFMT *

dsfmt

)

Generates a double precision pseudo random number ranging [0,1).

This function generates and returns a double precision pseudo random number which distributes uniformly in the range [0, 1).

Parameters

dsfmt

pointer to the dSFMT instance.

Returns

double precision floating point pseudorandom number

ytRNG_dSFMT_delete()

void ytRNG_dSFMT_delete

(

void *

dsfmt

)

Deletes the dSFMT random number generator instance.

Parameters

dsfmt

pointer to the dSFMT instance to be deleted.

ytRNG_dSFMT_new()

ytRNG_dSFMT * ytRNG_dSFMT_new

(

)

Generates an instance for dSFMT random number generator.

This initializes the random number generator with a default seed value (0).

ytRNG_dSFMT_new_init() is recommended to initialize the returning instance at once.
