SDVariable normal(String name, double mean, double stddev, DataType datatype, long[] shape)
Generate a new random INDArray, where values are randomly sampled according to a Gaussian (normal) distribution,
N(mean, stdev)
- mean - Mean value for the random array
- stddev - Standard deviation for the random array
- datatype - Data type of the output variable
- shape - Shape of the new random INDArray, as a 1D array (Size: AtLeast(min=0))
