计算多边形(凸凹)面积。 欢迎批评指正(Calculating polygon (convex and concave) area. Welcome criticism)

文章简述了一位大牛研究深度学习（Deep Learning）后的心得及见解(Article outlines a large cattle study deep learning (Deep Learning) after experiences and insights)

埃特金加速法 中国矿业大学理学院 计算方法实验5,还可以的(Aitken acceleration method China mining university faculty of science calculation method for the experiment 5, you can also)

C++程序求两点距离 可以点入坐标点(C++ program distance between two points)

压缩包包含三个文件： 全主元高斯-约当消元法程序AGJDN.m；基于全主元高斯-约当消元法的迭代求解病态矩阵方法AGJDNM.m；AGJDN.m的测试方程。 程序参考自：Fortran常用算法程序集（第二版） 徐世良编。AGJDN.m能求解部分病态矩阵，而AGJDNM.m对于我的测试矩阵效果不佳，但也一并上传，仅供参考。 错漏之处，还望指正。 (Gaussian-Jordan elimination base on all principal element.)

相场法材料计算的model C-pure对应的基础相场计算代码，初学者可取(The phase field calculation code corresponding to the model C-pure calculated by the phase field method material is suitable for beginners.)

只是一个课堂上做的九九乘法表，可能很多人做过(Just a class to do multiplication table, many people may have done)

说明：  在matlab环境下能进行各种曲线拟合的算法，非常好。(In the matlab environment to conduct various kinds of curve fitting algorithms, very good.)

说明：  Copula and tail dependence

说明：  CZT和FFT的C语言实现代码，能有效滤除谐波，噪声。获得信号的频率，是一种良好的频率测量算法。(CZT and FFT of the C language code, can effectively filter out harmonics and noise. Access to the signal frequency, is a good algorithm for frequency measurement.)
