FFT/IFFT 变换程序----------------(FFT/IFFT transformation process----------------)

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)

频率响应函数计算程序,通过输入结构的响应数据，识别结构的模态参数，matlab(frequency response function，)

编写一个使用KMP算法的字符串匹配程序。 使用方法：字符串匹配.exe -f xxx.txt -s xxx -f 指定要查找的文件 -s 指定要查找的字符串(Writing a string matching algorithm using KMP program. How to use: string matching exe-f xxx.txt-s xxx-f to specify the file you want to find-s to specify the search string)

复数的四则运算完整版，包括加减乘除，阶乘，开方等。。。(The plural arithmetic full version,, including addition, subtraction, multiplication, and division factorial, prescribing, etc...)

C++实现的FFT，详细，简单，内含多个测试类(using C++ implements fft，including serials class)

对于水轮机阀门开启、关闭的一瞬间，对于钢管有比较大的水击。该程序计算出了相对最大的水击压力。(For turbine valves opened, the closure of the moment, for a relatively large pipe water hammer. The program calculated the maximum relative pressure of water hammer.)

恒温减压沸腾UDF,一个基于压力计算的水蒸发UDF程序，请大家探讨一下(boiling udf of costant T and decreasing P)

用c++实现m次多项式的曲线拟合，改程序简单易懂，可读性强(it s easy)

说明：  fluent中作液体蒸发相变的udf，非常专业，证明可行(fluent in the evaporation of liquid phase transition for udf, very professional, proved to be feasible)
