VB自己编写的卡尔曼滤波程序源代码，每次变化数据源触发该子函数.-I have written Kalman filter VB source code, each data source that triggered the change subroutine.

Computation Method D phononic bandgap plane wave, Various kalman filter design, Is a two hidden layer back propagation neural network.

针对线性高斯系统，采用共轭分布实现量测噪声未知情况下的状态估计和噪声方差辨识。(For linear Gaussian system, a conjugate distribution is adopted to estimate system state and identificate measurement noise variance.)

VB自己编写的卡尔曼滤波程序源代码，每次变化数据源触发该子函数，初始定义完后得出滤波数值，然后自动计算出K+1时刻最优偏差，然后赋值给text1 也就是最优偏差，一直变化，而这个迭代由数据源的变化而触发驱动。(The source code of the Kalman filter program written by VB. Every time the data source changes, the sub-function is triggered. After the initial
