1.分别在两个图中画出δ(n)和δ(n-2)，其中-10≤n≤10，画出U（n）其中-10≤n≤10。 2.分别在两个图中画出x1(n)=cos(2π×20×0.01×n)，0≤n≤10和x2(n)=(0.8)n，1≤n≤6。 3.由上一题，计算y(n)=x1(n)+x2(n)，并画图。(1. Draw the figure at two δ (n) and δ (n-2), where-10 ≤ n ≤ 10, draw the U (n) where-10 ≤ n ≤ 10. 2. Respectively in the two Draw the figure x1 (n) = cos (2π × 20 × 0.01 × n), 0 ≤ n ≤ 10 and x2 (n) = (0.8) n, 1 ≤ n ≤ 6. 3. from the previous question, calculate y (n) = x1 (n)+ x2 (n), and drawing.)

主成分分析和偏最小二乘SquaresPrincipal成分分析（ PCA ）和偏最小二乘（ PLS ） ，广泛应用于工具。此代码是为了显示他们的关系，通过非线性迭代偏最小二乘（ NIPALS ）算法。 (Principal Component Analysis and Partial Least SquaresPrincipal Component Analysis (PCA) and Partial Least Squares (PLS) are widely used tools. This code is to show their relationship through the Nonlinear Iterative PArtial Least Squares (NIPALS) algorithm. )

说明：  混合整数二次规划(MixedInteger QuadraticProgramming,MIQP)问题最优化问题源代码(source code of MIQP problem)

主要是通过程序设计，设计简单驾驶员转向控制模型(Mainly through program design, simple design the driver steering control model)

用于处理音频信号 便于分习信号的频率等 有用消息(A facilitate stars learning signal frequency for processing an audio signal useful message)

说明：  搜索算法，matlab十大经典算法之一。数学建模常用算法，里面解释的非常清晰，读者自学可用。(Search algorithm is one of the ten classic algorithms of MATLAB. Mathematical modeling commonly used algorithm, which explains very clearly, the reader self-study available.)

参数假设检验：对差异进行定量的分析，确定其性质，是随机误差还是系统误差.为给出两者界限，找一检验统计量T，在H0成立下其分布已知。(Parameter hypothesis test: a quantitative analysis of the differences, to determine its nature, is random error or system error. Is given two boundaries, looking for a test statistic T, its distribution under the establishment of the H0 known.)

实现列主元高斯消去法的方程求解，主要针对压缩和非压缩矩阵(Equation solver to achieve out PCA Gaussian elimination, mainly for compressed and uncompressed matrix)

this is the code which is used apart from rls

本程序为一个实现MIMO-OFDM信道估计的程序，程序中采用的为2*2系统，可以换成其他系统(procedures for the realization of a MIMO-OFDM channel estimation procedures, procedures for the use of 2* 2 system, could be replaced with other systems)
