用matlab做的 回归分离器+数据 (Using matlab to do regression separator+ data)

matlab的87个实例，基本上涵盖了matlab得许多操作函数和图像处理方法，对大家的学习很有帮助。(87 instances of matlab, matlab have basically covered many operations functions and image processing method, all very helpful.)

QPSK调制与解调，运用MATLAB语言编写(QPSK modulation and demodulation using the MATLAB language)

i send the matlab codes for embedded zero tree and se partioning in hierarchial trees in image compression.I also send matlab code for speech compression using rabiner algorithm amd OFDM transceiver design.

this is matlab code that perform convex optimization for several objective function types

先得到一个定位初始估计值，再利用建立最大似然方程对这个定位初始估计值进行修正，从而得到更优定位结果值，方法更接近于最大似然方法。(Get the a position initial estimate, re-use to establish the maximum likelihood equations corrected for positioning the initial estimates, resulting in better positioning the resulting value is closer to the maximum likelihood method.)
