Create a random array sampled from normal distribution.
The type of engine used is defined by af::randomEngine.
The data is centered around 0.
◆ af_randn()
- Parameters
-
[out] out generated array [in] ndims number of dimensions [in] dims array containing sizes of the dimension [in] type type of array to generate
- Returns
- AF_SUCCESS, if function returns successfully, else an af_err code is given
◆ af_random_normal()
C Interface to create an array of normal numbers using a random engine.
- Parameters
-
[out] out pointer to the returned object [in] ndims number of dimensions [in] dims C pointer with ndimselements; each value represents the size of that dimension[in] type type of the af_array object [in] engine random engine object
- Returns
- AF_SUCCESS, if function returns successfully, else an af_err code is given
◆ randn() [1/6]
C++ Interface to create an array of random numbers normally distributed.
