code for object extraction using matlab

说明：  这是一个关于扩展卡尔曼滤波的源程序，可以帮助初学者学习该滤波算法(This is an extended Kalman filter on the source, can help beginners learn the filtering algorithm)

定义法计算计算Lorenz系统lyapunov指数，结果比较精确！ 可以改为任意3维动力系统的lyapunov指数的计算程序！(Define of the method to calculate the Lorenz system lyapunov index, accurate results! Can be changed to any 3-dimensional dynamical systems lyapunov index calculation program!)

intro to matlab.contains basic matlab commands

模糊isodata算法matlab程序；fuzzyisodata的matlab程序。很好很实用。(fuzzyisodata program)

这是关于数字水印的攻击例程！经过调试，可以放心使用！(This is on digital watermarking attacks routines! After debugging, can be assured use!)

仿真了QPSK，16PSK与QAM信号在不同通信信道中的误码率。(simulation of QPSK, 16QAM and QAM signals in different communication channel bit error rate.)

介绍了在多通道下的多普勒频移解决方案，能很好的解决实际多径频移问题(Describes the multi-channel Doppler frequency shift under the solution, can be very good to solve practical multi-path frequency-shift problem)

通过比较传统仅移相的波束与移相+理想延时的波束，来说明述S波段宽带阵列孔径渡越现象(To demonstrate the aperture effct of S_band windband array, this programe comparing the beam pattern of the traditional beamforming method "phase shifting only" with that of "phase shifting+ ideal delay".)
