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)

计算方法实验，通过编程实现埃特金加速法，一般迭代法，牛顿法的收敛次数的计算(calculated experiment, Programming Aitken acceleration method, the general iterative method, the convergence of Newton's method of calculating the number of)

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)

用于处理电力系统中含有4个节点的随机潮流计算(Four nodes to deal with the random flow calculation)

说明：  实现重力式热管换热器设计计算功能，简单按照设计任务书，给出所需热管的结构尺寸，涉及的热管蒸发段和冷凝段长度分别为1m，绝热段长度30cm，内径20cm，外径25cm，热管工质为水。(Realize the gravity heat pipe heat exchanger design and calculation functions , simple design in accordance with the mission statement , given the size of the required structure of the heat pipe , heat pipe evaporator and condenser section lengths were involved 1m, adiabatic length 30cm, inner diameter 20cm, 25cm outside diameter heat pipe working fluid is water. )

偏最小二乘法中的交叉有效性计算,看看，可能有用(PLS cross-validity of the calculation, see, may be useful)

提供函数能进行1维2维的FFT，输入输出的序列长度应为2的整数次方倍(Provides functions can be one-dimensional two-dimensional FFT, sequence length input and output should be an integer power of 2 times)

基于时间序列法的超短期电力负荷预测 利用时间序列法进行数学建模(Mathematical modeling based on very short-term power load time series forecasting using time series method)

本程序用在测试采煤机煤矸识别系统中，验证小波算法(Wavelet Algorithm for caving coal)

说明：  这是一个ACM试题中的算法，叫分而治之算法，上面有PPT还有实例代码，希望喜欢ACM的同学可以喜欢(This is a Question in the ACM algorithm, called divide and conquer algorithms, there are examples of the code above, there are PPT hope that students like to be like the ACM)
