双线性变换算法

输入阶次 ，采样时间 ，控制变量 （ 时 ＝1， 时 ＝0）

b1为s函数或z函数多项式的系数,先输入分子的系数（从高次幂至低次幂，高阶系数为零的，应输入0，各系数之间用空格键隔开），再输入分母的系数（从高次幂至低次幂，高阶系数为零的，应输入0，各系数之间用空格键隔开），均存到b1内。

-Bilinear transform algorithm input order, the sampling time, control variables (time = 1, when = 0) b1 function for s or z function polynomial coefficient, the coefficient of the first input elements (from the high power to low power of , high-coefficient of zero, should be type 0, the coefficient between the key separated by a space), and then type the denominator of the coefficient (from the high power to low-power, high-coefficient of zero, should be type 0, between the coefficient of keys separated by spaces), are kept within the b1.
