System-identification
系统辨识作业 考虑如下模型
z(k)-1.5z(k-1)+0.7z(k-2)=u(k-1)+0.5u(k-2)+v(k)
其中v(k)是均值为0，方差为1的白噪声。根据模型生成数据，采用递推最小二乘法对模型参数进行辨识，要求绘出各参数随时间的变化曲线。
("System identification" computer test 。Consider the following model
Z (k) to 1.5 of z (k- 1)+ 0.7 z (k- 2) = u (k- 1)+ 0.5 u (k- 2)+ v (k)
The v (k) is the mean to 0, the white noise variance 1. Generate data according to the model, the recursive least squares method is adopted to model parameters are identified, draw the parameters changing with time curve.

说明： 问题的提出：根据“心”形曲线的数学参数方程，绘制曲线并输出屏幕。在各坐标点处循环显示“LOVE”的各字母。
编程思路：“心”形曲线的数学参数方程为:
(Of the problem: According to the " heart" -shaped mathematical curve parameter equation, drawing curves and output screen. Coordinates of points in the cycle show " LOVE" in the letter. Programming idea: " heart" -shaped mathematical curve parameter equation:)
