示例1: JScience_IsPossibleToSolveForUnknownValueOfX_ReturnsTrue
import org.jscience.mathematics.number.Real; //导入依赖的package包/类
@Test
public void JScience_IsPossibleToSolveForUnknownValueOfX_ReturnsTrue(){
// Defines two local variables (x, y).
Variable<Real> varX = new Variable.Local<Real>("x");
Variable<Real> varY = new Variable.Local<Real>("y");
Variable<Real> varA = new Variable.Local<Real>("a");
// f(x) = ix² + 2x + 1
Polynomial<Real> x = Polynomial.valueOf(Real.ONE, varX);
Polynomial<Real> fx = x.pow(2).times(Real.valueOf(2)).plus(x.times(Real.valueOf(4)).plus(Real.valueOf(0.5)));
System.out.println(fx);
System.out.println(fx.pow(2));
System.out.println(fx.differentiate(varX));
System.out.println(fx.integrate(varY));
System.out.println(fx.compose(fx));
// TO DO: Solve for x.
// See: http://jscience.org/api/overview-summary.html#TUTORIAL
// // Calculates expression.
// varX.set(Complex.valueOf(2, 3));
// System.out.println(fx.evaluate());
