Generate
public Generate(TensorType type, java.util.function.Function<java.util.List<java.lang.Long>,java.lang.Double> generator)
Creates a generated tensor- Parameters:
type
- the type of the tensorgenerator
- the function generating values from a list of numbers specifying the indexes of the tensor cell which will receive the value- Throws:
java.lang.IllegalArgumentException
- if any of the tensor dimensions are not indexed bound
