一种用于谐波分析的重采样方法，同过matlab仿真实现(For the resampling method of harmonic analysis, Matlab simulation to achieve the same over)

EKF程序，可以应用于粒子滤波程序进行效果比较(EKF procedure can be applied to compare effects of particle filtering procedure)

rapresents AR(1) model. dsp and correlation funtion of the ar(1) MODEL. it uses randn to generate vector and filter to do ar(1).

this matlab code is useful for hill climbing algorithm.

本人编的图像配准算法，使用相关算法，模板在参考图像上移动(I compiled image registration algorithm, using the correlation algorithm)

for removal used to remove the fog and get clear image

post filter,complete matlab program

仿真程序：首先需要用一个随机发生器产生（0.1）内的均匀随机数，然后再将该序列映射到对应的幅度电平｛Am｝。然后将这个范围再分成4个相等的区间，这些子区间分别对应于4个信号比特的符号00，01，10，11。检测器观察到r=Am+n，并且计算r和4种可能传输的信号幅度之间的距离，它的输出Bm就是相应于最小距离的信号电平。Bm与真正的的传输信号幅度比较，差错计数器用来对检测器产生的差错计数。(Simulation program: first need to use a random generator (0.1) the uniform random number, then the sequence is mapped to the corresponding amplitude level {Am}. Then this range has been divided into four equal intervals, these sub-intervals corresponding to four signal bits of the symbol 00,01,10,11. Detector observed r = Am+ n, and calculate r and 4 possible transmission distance between the signal amplitude, its output corresponding to the minimum distance Bm is the signal level. Bm and the real rate of transmission of the signal comparison, error detection counter is used to generate the error count.)

这是一个圆阵列声阵列仿真程序，信号处理，希望对大家有用。(This is a circular array of acoustic array simulation program, signal processing, we want to be useful.)

xerrorbar - Just like errorbar, but for uncertainty in x
