实现1到1000位的大数运算（包括加减乘除和浮点数运算），运行环境是vs2005(1-1000, large number operations (addition, subtraction and floating-point), the operating environment is vs2005)

湍流模型re计算流体力学软件udf 可以用于修改UDF文件(turbulence model FLUENT)

一个仓本模型计算程序，用于计算奇异态和序参量(a program of kuramotto)

录音程序，音频录音fft程序，并加界面显示(radio record code)

ansys 求解桥梁结构弯矩响线的命令流，非常实用(ansys solving the stream of the bridge structure bending ring line command is very useful)

用于焊接模拟的fluent的双椭球体热源UDF程序。(For welding simulation fluent double ellipsoid heat source UDF program.)

this source code is use to calculate resister capacitor and inductor

用吉尔方法积分一阶微分方程组的初值问题。(Gill method with integral equations of first order initial value problem.)

同时辨识模型阶次及参数算法。用阶次递推算法，结合AIC法——利用赤池信息准则辨识上例的模型阶次和参数。(At the same time identify model order and parameters algorithm. By order recursive algorithm, combined with AIC method- the use of Akaike information criterion to identify the cases of the model order and parameters.)

最小二乘法拟合进行n次多项式拟合，N用来控制拟合的次数，例如N=5时进行4次多项式拟合，还回的是拟合系数(Least squares fit polynomial n times, N is used to fit the number of control, e.g., N = 5 When quartic polynomial fitting, further back are fitting coefficients)
