说明：  几种模幂算法，有传统模幂，SMM模幂，基于2的K次方的模幂和最一般的模幂算法，还有为这些模幂算法建立的WINDOWS对话框。可以方便的运行。(algorithm, the traditional mode power, SMM Modular Power, Based on two of the K-th power module and the most common mode power algorithm, These modules also for the establishment of the algorithm Power Windows dialog box. To facilitate the operation.)

C语言实现Matlab中interp1和interp2中的功能。(Interp1 and interp2 in Matlab, C language the function.)

四阶龙格库塔法，用C++编写，很有参考价值(Fourth-order Runge-Kutta method, written in C, a good reference)

说明：  你输入一个长方体的长和宽以及高，就可以输出他的面积(input height，width，length，output volume)

可进行最小二乘法线性拟合输出，包含源代码及生成后的程序(Least-squares linear fit can be output)

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)

各种数值积分，龙贝格积分。反常积分。高斯积分。三重积分。(Various numerical integration Romberg integration. Improper integrals. Gaussian integral. Triple integral.)

利用pid算法控制电机转速，转速可调，数码管显示，初学者实用(Using PID algorithm to control motor speed, adjustable speed, digital display, beginners practical)

适用于大型稀疏矩阵 矩阵转置 c语言 来自于有限元方法编程(From the finite element method suitable for large-scale sparse matrix matrix transpose c language programming)

分数值分析的一些ppt课件，很有用，在学习C的时候，可以用到这些博大精深的思想(Fractional value analysis ppt courseware, useful when learning C, you can use these profound thought)
