public Complex getA() {//finds A coef
    Complex psi1 = this.psi[0];
    Complex psi2 = this.psi[1];
    double x1 = this.xvals[0];
    double x2 = this.xvals[1];

    Complex A = (psi2.multiply(Exp(Complex.I.multiply(Math.sqrt(kappa) * x2))));
    A = A.subtract(psi1.multiply(Exp(Complex.I.multiply(Math.sqrt(kappa) * x1))));
    Complex divisor = Exp(Complex.I.multiply(2 * Math.sqrt(kappa) * x2))
            .subtract(Exp(Complex.I.multiply(2 * Math.sqrt(kappa) * x1)));
    A = A.divide(divisor);/*w w  w. j  ava  2s . com*/
