说明：  自适应步长龙格库塔法求解常微分方程，main.c内容根据自己需要改变，待求解方程为derivs，需要使用者自己编写(Adaptive step size Runge Curta Fa for solving ordinary differential equations)

C语言矩阵求逆模块,输入矩阵调用此模块即可求出对应的逆矩阵(C language matrix inversion module)

C++程序求两点距离 可以点入坐标点(C++ program distance between two points)

一个计算结构波浪力的程序，小直径桩柱结构，中等直径桩柱结构，多桩结构(A program for calculating the wave force of the structure, a small-diameter pile structure, a medium-diameter pile structure, a multi-pile structure)

mimo系统中在高信噪比下，一个发射天线，两个接收天线的性能仿真。(mimo systems at high signal to noise ratio, a transmitting antenna, two receive antenna performance simulation.)

用无网格法计算VAN DE POL 振子(calculate van de pol oscillator by using meshless method)

模拟退火算法，地球物理反演，非线性反演算法(Simulated annealing algorithm)

fractal compression using wavelet

全局牛顿-拉普森方法求解非线性方程组，自动搜索步长，进一步保证了程序的收敛(Global Newton-Raphson method for solving nonlinear equations. The steps can be found automatically. The convergence is better than the common Newton-raphson method.)

程序提示用户输入两个数,然后它将输出这两个数字的和、差、积、商、以及余数，分十进制和十六进制两种格式 (The program prompts the user to enter two numbers, then it will be the output of these two numbers and difference, product, quotient, and the remainder, and decimal and hexadecimal two formats)
