How to use

selfExpand

method

in

jscl.math.function.ImplicitFunction

public Generic derivative(int n) {
  int c[] = new int[derivations.length];
  for (int i = 0; i < c.length; i++) {
    if (i == n) c[i] = derivations[i] + 1;
    else c[i] = derivations[i];
  }
  return new ImplicitFunction(name, parameters, c, subscripts).selfExpand();
}

public Generic antiDerivative(int n) throws NotIntegrableException {
  int c[] = new int[derivations.length];
  for (int i = 0; i < c.length; i++) {
    if (i == n) {
      if (derivations[i] > 0) c[i] = derivations[i] - 1;
      else throw new NotIntegrableException(this);
    } else c[i] = derivations[i];
  }
  return new ImplicitFunction(name, parameters, c, subscripts).selfExpand();
}
