kalman滤波器的C源代码，kalman滤波器的用途很广，比如卡尔曼滤波是一种高效率的递归滤波器(自回归滤波器), 它能够从一系列的不完全包含噪声的测量，估计动态系统的状态。-kalman filter C source code, kalman filter uses a very wide, such as the Kalman filter is an efficient recursive filter (autoregressive filter), it can not completely contain a series of noise measurements, estimated dynamic system state.
