Class NDArrayCreationUtil

java.lang.Object

org.nd4j.linalg.checkutil.NDArrayCreationUtil

public class NDArrayCreationUtil
extends Object

This class contains utility methods for generating NDArrays for use in unit tests The idea is to generate arrays with a specific shape, after various operations have been undertaken on them So output is after get, reshape, transpose, permute, tensorAlongDimension etc operations have been done
Most useful methods:
- getAllTestMatricesWithShape - getAll4dTestArraysWithShape - getAll4dTestArraysWithShape
