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)

最小二乘法拟合形如f(x)=(a+bx)/(1+cx)的函数（9.2.2(1))，并解决人口预测问题(9.2.2(2))(Least squares fit of the form f (x) = (a+bx)/(1+cx) function (9.2.2 (1)), and to solve the population prediction problem (9.2.2 (2)))

用于求解超定方程组最小二乘解，稳定性高，速度快(To get the least square solution of superlattice dislocation.)

本程序包括：DFT（离散傅里叶变换），FFT（快速傅里叶变换），IFFT（快速傅里叶逆变换），conv（卷积：圆周卷积、线性卷积），主要应用于信号处理，既可以对实序列做上述操作，也可以对复序列。(This process includes: DFT (Discrete Fourier Transform), FFT (fast Fourier transform), IFFT (inverse fast Fourier transform), conv (convolution: circular convolution, linear convolution), mainly used signal processing, either on the actual sequence to do the operation, can also be complex sequence.)

很好很实用的信号处理程序。适合学习和科研参考使用。(Very good very useful signal processing. Suitable for learning and scientific research use and reference.)

This program is used to find the union, intersection and exclusive OR for given two sorted arrays.

数值计算实例，主要有LU分解，龙格库塔法，高斯分解法，欧拉法，曲线拟合，曲线插值(Numerical example)

fluent 软件动网格计算的CAS文件和二次开发程序。用来计算一个蜜蜂翅膀摆动时周围流畅的变化。(fluent moving grid computing, software, documents and secondary development of CAS procedures. Used to calculate the wings of a bee when swinging around the smooth changes.)

一个实现sor超松弛迭代法的c语言算法，可以帮助新手完成矩阵计算(A C language algorithm for realizing over relaxation iterative method)
