蚁群聚类算法，很有用的优化算法程序。希望对大家有用。(Ant colony clustering algorithm, a useful optimization process. Want to be useful to everyone.)

这个源代码是关于基本遗传算法求解一维无约束优化问题的代码(This source code is on a one-dimensional basic genetic algorithm code for unconstrained optimization problems)

1、观察采样引起的混叠。 2、判别离散时间系统的时不变性。 3、利用卷积计算信号通过FIR滤波器的输出，并观察输出信号的input-on暂态、input-off暂态和稳态阶段。 (One to observe the sampling due to aliasing. 2, determine the time invariant discrete-time systems. 3, the use of convolution calculation of the signal through the FIR filter output, and observe the output signal of the input-on transient, input-off transient and steady-state phase.)

说明：  ofdm调制，仿真以及系统的性能的分析，估计系统的误码率(ofdm modulation, simulation and analysis of system performance, the BER is estimated)

We construct a generalization of affine-scaling vector fields for matrix linear programming problems. We discuss various properties of these vector fields and suggest a generalization of Dikin s algorithm.

1. 按照式计算相似性矩阵 2. 排除自身的相似度 3. 按照式计算归一化矩阵 4. 按照式计算归一化拉普拉斯图矩阵L 5. 计算L的特征向量，将前个特征值最大的向量按列放置成一个矩阵，即依次为前个特征值最大的特征向量 6. 归一化X形成矩阵Y 7. 对矩阵Y按每行为一个数据点，进行k-means聚类，第行所属的类就是原来所属的类。(1. similarity matrix based on formula computation 2. rule out your own similarity. 3. normalized matrix based on formula computation 4. normalized formula Laplasse matrix L according to formula. 5. Calculate the eigenvectors of L. Place the vectors with the largest eigenvalues in columns into a matrix, that is, the eigenvectors with the largest eigenvalues in turn. 6. normalized X formation matrix Y 7. K-means clustering is applied to matrix Y according to one data point per behavior. The first row belongs to the original class.)
