float* for vsRngChiSquare double* for vdRngChiSquare |
Vector of n random numbers with chi-square distribution |
The vRngChiSquare function generates random numbers with chi-square distribution and ν degrees of freedom, ν ∈N, ν > 0.
The probability density function is:
The cumulative distribution function is:
- VSL_ERROR_OK, VSL_STATUS_OK
-
Indicates no error, execution is successful.
- VSL_ERROR_NULL_PTR
-
stream is a NULL pointer.
- VSL_RNG_ERROR_BAD_STREAM
-
stream is not a valid random stream.
- VSL_RNG_ERROR_BAD_UPDATE
-
Callback function for an abstract BRNG returns an invalid number of updated entries in a buffer, that is, < 0 or > nmax.
- VSL_RNG_ERROR_NO_NUMBERS
-
Callback function for an abstract BRNG returns 0 as the number of updated entries in a buffer.
- VSL_RNG_ERROR_QRNG_PERIOD_ELAPSED
-
Period of the generator has been exceeded.
- VSL_RNG_ERROR_NONDETERM_NRETRIES_EXCEEDED
-
Number of retries to generate a random number by using non-deterministic random number generator exceeds threshold.
- VSL_RNG_ERROR_ARS5_NOT_SUPPORTED
-
ARS-5 random number generator is not supported on the CPU running the application.
