工程算法 这是一个很有用的工程数值算法集锦(Engineering algorithm this is a useful collection of engineering numerical algorithms.)

扩展卡尔曼滤波与无迹卡尔曼滤波的跟踪滤波性能的比较()

训练SVR模型做预测,可调整训练集和测试集比例及SVR参数，预测性能用MAP反映(The training SVR model can be used for prediction. The proportion of training set and test set and the parameters of SVR can be adjusted. The prediction performance can be reflected by MAP.)

用VB实现数值积分的算法集,包括梯形求积法,反常积分,三重积分,龙贝格方法,辛卜生方法等6种方法,(VB is used to realize the algorithm set of numerical integration, including trapezoidal quadrature method, anomalous integral, triple integral, Romberg method, Simbsen method and so on.)

 环保大数据的处理对环保行业非常重要，本人编写了如何整合环保大数据的问题

本程序主要是针对超大整型数据的基础加、减、乘运算，运算位数可达10000位，同时也支持使用者进行修改扩展至更大位数

此代码是针对数据库教材的源代码，包括求“输入的两个数的最大公约数和最小公倍数”、“输入工资输出工资水平”。程序在Access上得到了验证，也可以移植到其他数据库上。(This code is aimed at teaching book of source code, including database for "input the two Numbers when the largest and smallest LCD", "input output wages." wages Program in the Access is verified, also can be transplanted into other database.)

用最小二乘法计算分形图案的维数,试试看怎么样,请多包涵！！(Use the least square method to calculate the dimensions of fractal patterns, try how, please include more!)

计算七类窗函数并给出归一化对数幅频曲线,同时也是利用窗函数法设计FIR滤波器的程序MDEFIR1所调用的子程序MWINDO(Seven kinds of window functions are calculated and normalized logarithmic amplitude-frequency curves are given. At the same time, it is also the subroutine MWINDO called by the program MDEFIR1 of designing FIR filter by using window function method.)

说明：  此压缩文件包含2002年-2017年200多个地级市资本存量的数据，里面有详细的计算过程与说明。(This document contains the capital stock data of more than 200 cities in 2002-2017, including detailed calculation process and description, which is convenient for scholars to understand and master)
