说明：  harrisi 算法，用此算法可以快速在图像中寻找到角点，快速 准确(harrisi algorithm)

主要介绍求根music算法，对于初学者可以多看一下。(Mainly introduces roots music algorithm for for beginners can read it.)

多用户MIMO预编码技术：块对角化BD，分别采用SVD技术，最大似然检测，最小均方误差检测的误码率性能仿真代码。里面有代码，仿真图等。(Multi-user MIMO precoding techniques: block diagonalization BD, respectively, using the SVD technique, maximum likelihood detection, the minimum mean square error detection BER performance simulation code. There are code, simulation maps.)

first, this project simulates cdma network using 63 gold code over Rayleigh fading channel.then ,compares rake receiver performance with ordinary receiver and theory awgn and theory Rayleigh channel . finally , we observe decreasing ber when number of users is increasable.

In numerical analysis, the secant method is a root-finding algorithm that uses a succession of roots of secant lines to better approximate a root of a function f.(The secant iteration to find the zero of some non-linear function converges to zero if appropriate starting values are chosen. Although the convergence rate is not as good as the one of the Newton method, it may sometimes converge when Newton fails. The funtion should be defined as an inline function and two starting values are required to start the iteration. Please enter help secant from the Matlab prompt for usage information and examples. )

matlab 的dsp的编程，对DSP的开发有点÷一定的一处(Code on DSP with matlab,may be have a little useful for you!)
