卡尔曼滤波多元线性回归方程的Matlab代码如下所示:
```matlab
function [x_est, P_est = kalman_filter(A, B, H, Q, R, x, P, z)
% 预测步骤
x_pred = A * x;
P_pred = A * P * A' + Q;
% 更新步骤
K = P_pred * H' * inv(H * P_pred * H' + R);
x_est = x_pred + K * (z - H * x_pred);
P_est = (eye(size(A)) - K * H) * P_pred;
end
```
其中,输入参数为:
- A:状态转移矩阵
- B:控制输入矩阵(如果没有控制输入,可以设为0)
- H:测量矩阵
- Q:系统过程噪声协方差矩阵
- R:测量噪声协方差矩阵
- x:初始状态向量
- P:初始状态协方差矩阵
- z:测量向量
输出结果为:
- x_est:估计的状态向量
- P_est:估计的状态协方差矩阵
请注意,上述代码是一个基本的卡尔曼滤波器实现,你可以根据实际情况对其进行修改和扩展。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
