说明：  这是用MATLAB写的一个RD算法的程序，不知道有人上传过没有，希望有用(This is used to write a MATLAB algorithm RD procedure, I do not know it was not uploaded, I hope useful)

gbvs 提取显著区域，进行其他的程序编写。在matlab上运行，先安装，后可以直接运行(gbvs select main object)

[x,f]= L01p_e(c,A,b,N)用枚举法求解下列 0-1线性规划问题min f=c *x, s.t. A*x<=b,x的分量全为整数0或1, 其中N表示约束条件 Ax ≤ b中的前N个是等式，N= 0时可以省略。 返回结果x是最优解，f是最优解处的函数值。 ([X, f] = L01p_e (c, A, b, N) with the following enumeration method for solving linear programming problems 0-1 min f = c ' * x, st A* x < = b, x is an integer of all components 0 or 1, where N represents the constraints Ax ≤ b in the equation of the first N, N = 0 can be omitted. Return result x is the optimal solution, f is the function value at the optimal solution.)

滤波器仿真 matlab 画图 真是凑不够20个字了(Minato filter simulation matlab drawing is really not enough words of the 20)

用来正演超临界角情况下的地震反射特征，用来分析地震反射的AVO特征等领域。(Forward simulation of wide-angle Reflection uesd in AVO analysis. )

PCA特征脸 可以获得ORL库的特征连图像。(PCA face)

信号为两个正弦信号加高斯白噪声，各正弦信号的信噪比均为10dB，长度为N，信号频率分别为 和 ，初始相位 ，取 ， 取不同数值：0.3，0.25。 为采样频率。分别用Levinson递推法和Burg法进行功率谱估计，并分析改变数据长度、模型阶数对谱估计结果的影响。(Signal into two sinusoidal signals applied Gaussian white noise, the SNR of each sinusoidal signals are 10dB, a length of N, respectively, and the signal frequency, initial phase, take, take different values: 0.3,0.25. It is the sampling frequency. Respectively Levinson recursion method and Burg method for power spectrum estimation, and change the length of the data analysis, the impact of model order estimation result spectrum.)
