Class InputFieldArray2D

java.lang.Object

org.encog.util.normalize.input.BasicInputField

org.encog.util.normalize.input.InputFieldArray2D

All Implemented Interfaces:

java.io.Serializable, HasFixedLength, InputField

public class InputFieldArray2D
extends BasicInputField
implements HasFixedLength

An input field that comes from a 2D array. The first dimension of the array will be used to read each successive row. The second dimension is fixed, and specified in the constructor. You would create multiple InputFieldArray2D object to read each of the "columns" stored at each row. Note: this input field will not be persisted to an EG file. This is because it could point to a lengthy array, that really has no meaning inside of an EG file.
