3D-FDTD

this is matlab program for showing the result of quasi ostbc

利用matlab采用最小二乘法很好的实现了振动阻尼的数值求解(Least square method using matlab realize very good vibration damping of the numerical solution)

说明：  软入软出译码算法实现 (SISO （soft input ，soft output） )

用MATLAB编写求解伪距定位方程的程序，对实际数据进行处理，解算出接收机的位置及钟差信息。提供8个通道的两组数据如下，X, Y, Z 为WGS-84坐标系下各通道所跟踪卫星的坐标，Range为与之对应的校正后的伪距测量值。(Using MATLAB pseudorange positioning equation solver, and the actual data processing, solution and calculate the position of the receiver clock error information. 8 provides the following two data channels, X, Y, Z coordinates of the WGS-84 coordinate system of each channel of the satellite tracking, Range for the pseudo-range measurements corresponding corrected.)

说明：  基于前馈补偿的PID控制算法，使用m文件编写，很简单的例子(PID control algorithm based on feedforward compensation)

credit risk prediction

无迹卡尔曼滤波用于车辆中跟踪定位，匀速直线运动(Trackless Kalman Filter for Tracking and Locating in Vehicles and Uniform Linear Motion)

k-means algorithm clustering

JPDA的matlab程序 可以使用 效果不错(JPDA matlab )

通过用类似于阶跃折射率型光纤的理论，计算光子晶体光纤的基模模式折射率和色散。 (By analogy with the theory of step-index fibers, the effective index of the fundamental mode and the dispersion of PCF can be calculated. )
