Examples of cern.colt.function.DoubleDoubleFunction.apply()

cern.colt.function.DoubleDoubleFunction.apply()
Applies a function to two arguments. @param x the first argument passed to the function. @param y the second argument passed to the function. @return the result of the function.

  double b = 0.2;
  double v = Math.sin(a) + Math.pow(Math.cos(b),2);
  System.out.println(v);
  DoubleDoubleFunction f = F.chain(F.plus,F.sin,F.chain(F.square,F.cos));
  //DoubleDoubleFunction f = F.chain(plus,sin,F.chain(square,cos));
  System.out.println(f.apply(a,b));
