用C++编写的一维和二维快速傅里叶变换程序(Prepared with C++ one-dimensional and two-dimensional fast Fourier transform procedure)

本算法是求取点到曲线的距离，希望对大家有帮助(the algorithm is to strike a point of the distance curve, and I hope to be helpful)

求实对称矩阵的特征值特征向量，内有读入数据文件。(Realistic symmetric matrix eigenvalue eigenvector, there are read into the data file.)

对于协方差矩阵的一种计算方法，对于地震中的反演约束算法能起到很好的作用。(For a kind of covariance matrix calculation method)

说明：  神经网络算法，希望能对大家有点点帮助，可以相互交流(Neural network algorithm, I hope everyone can have little bit of help, they communicate with each other)

说明：  Fractal分形，简短的代码，清晰可用(Fractal)

任意数学表达式计算的源码及测试软件 (Calculation of arbitrary mathematical expression of the source code and test software)

Fractional knapsack problem, Greedy algorithm

差分进化算法，有测试函数，是遗传算法的改进算法，收敛快，精度高。(Differential evolution algorithm, a test function, is an improved genetic algorithm algorithm, fast convergence, high precision.)

说明：  实现快速离散傅里叶变换，即FFT,很有用的程序(Fast discrete Fourier transform, namely, FFT, very useful program)
