Class AsinhTransformer

java.lang.Object
  org.apache.commons.nabla.algorithmic.forward.functions.AsinhTransformer

All Implemented Interfaces:

MathInvocationTransformer

public class AsinhTransformer
extends Object
implements MathInvocationTransformer

Differentiation transformer for the asinh function invocation instructions.

As of java 6, the JVM does not supply an inverse hyperbolic sine function (see bug 4919337), so this generator will not be triggered for java 6 and below.
