说明：  进退法，也成成功--失败法，是最优化方法的一种，用于确定区间(Advance and retreat method, have become a success- failure of law is a kind of optimization method used to determine the range)

here i have provided a matlab code in which we have the gold price of laast 4 yrs.we have predicted and showed it using a matlab code.

字母识别的一种应用并配有简单的分类器及基于BP网络的英文字母识别系统(Letters of application and identify with simple classifier based on BP neural network, and the English alphabet recognition system)

关于Mass-Damper-Spring System 的鲁棒控制源代码(About Mass-Damper-Spring System Robust Control of source code)

说明：  DVHOPE算法 网络技术中经典算法 适合初学者(DVHOPE algorithm for network technology in the classical algorithm for beginners)

信号经过两个独立的信道传输，两个信道的信道复增益分别为 和 。 是独立同分布的复高斯随机变量，实部虚部独立、均值为0，实部虚部的方差都是1。采用某分集技术后输出的信噪比为 ，其中 是常数， 是在 之间均匀分布的随机变量。请就不同的 、 ，用仿真的方法画出 的累积分布函数。(signal after two independent Channel Tunnel, Channel 2 Channel Minute respectively, and gain. Independence is the same complex Gaussian distribution of random variables, is the imaginary part of the Department of independence, mean 0 and the real part of the imaginary part is a variance. Using a diversity of the output signal-to-noise, which is constant, is the uniform distribution between random variables. Please different, and simulation methods paint the cumulative distribution function.)
