org.nd4j.linalg.string.NDArrayStrings

public class NDArrayStrings
extends Object

String representation of an ndarray. Printing will default to scientific notation on a per element basis - when absolute value is greater than or equal to 10000 - when absolute value is less than or equal to 0.0001 If the number of elements in the array is greater than 1000 only the first and last three elements in a dimension are included
