public class R1ContinuousBall
extends R1Continuous

R1ContinuousBall extends the Continuous R¹ Banach Space by enforcing the Closed Bounded Metric. The Reference we've used is:

• Carl, B., and I. Stephani (1990): Entropy, Compactness, and the Approximation of Operators Cambridge University Press Cambridge UK

It provides the following Functionality:

• Construct a R1ContinuousBall Instance of Unit Radius
• R1ContinuousBall Constructor
• Retrieve the Radius Norm
