AFAPI af_err af_randn | ( | af_array * | out,
|  | const unsigned | ndims,
|  | const dim_t *const | dims,
|  | const af_dtype | type
| ) |  |

Parameters

  [out] | out | is the generated array
  [in] | ndims | is size of dimension array `dims`
  [in] | dims | is the array containing sizes of the dimension
  [in] | type | is the type of array to generate

AFAPI array af::randn | ( | const dim4 & | dims,
|  | const dtype | ty = `f32`
| ) |  |

Parameters

  [in] | dims | is the dimensions of the array to be generated
  [in] | ty | is the type of the array

Returns
  array of size `dims`

Examples:
  heston_model.cpp, and monte_carlo_options.cpp.
