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 | The generated array |
[in] | ndims | Size of dimension array dims |
[in] | dims | The array containing sizes of the dimension |
[in] | type | The type of array to generate |
◆ af_random_normal()
C Interface for creating an array of normal numbers using a random engine.
- Parameters
-
[out] | out | The pointer to the returned object. |
[in] | ndims | The number of dimensions read from the dims parameter |
[in] | dims | A C pointer with ndims elements. Each value represents the size of that dimension |
