循环普，用于检测信号，有一定的效果，希望对大家有用(ofdm detection)

清华大学数学实验之数值积分幻灯片与MAT源码(Tsinghua University, numerical integration of the math test slides with the MAT-source)

说明：   模拟退火算法求函数 f(x)的最小值点， 且 l <= x <= u f为待求函数，x0为初值点，l，u分别为搜索区间的上下限，kmax为最大迭代次数 q为退火因子，TolFun为函数容许误差 算法第一步根据输入变量数，将某些量设为缺省值( Simulated annealing algorithm of a function f (x) the minimum point, and l &lt = x &lt = u f is the unknown function, x0 as the initial point, l, u, respectively, lower and upper limits for the search interval, kmax is the maximum q iterations for the annealing factor, TolFun as a function of allowable error algorithm is the first step according to the number of input variables, set default values for certain amount of)

对输入的语音信号进行分帧处理，低通滤波，中心削波，求自相关函数最后得到基音轨迹。(Speech input signal framing processing, low-pass filtering, center clipping, seeking autocorrelation function finally got the pitch trajectory.)

偏最小二乘法PLS广泛应用于很多领域。这个程序包提供了一个函数，使用非线性迭代偏最小二乘法NIPALS算法，实现PLS回归。同时包含NIPALS算法的教程(PLS PLS is widely used in many areas. This package provides a function, use of non-linear iterative partial least squares algorithm NIPALS achieve PLS regression. NIPALS algorithm contains tutorials)

经验模态分解（EMD），对imf进行分析，再采用类小波阈值去噪。(Empirical Mode Decomposition (EMD), were analyzed for the imf, then using class wavelet thresholding.)

说明：  智能飞信器的空间路径规划，通过MATLAB仿真，有具体结果。(The spatial path planning of the intelligent femtograph, through MATLAB simulation, has specific results.)

这个是一个排序熵的程序，它能够达到信息熵的目的，算是一个改进的方法。应用起来比较方便(This program is a sort of entropy, it can achieve the purpose of information entropy can be regarded as an improved method. Was easier to apply)
