电力系统中随机生产模拟中使用，为以后使用等效电量函数积分创造基础(Power system probabilistic production simulation used to create the foundation for the future use of the equivalent power function integral)

双音多频信号，根据输入的音频信号判断实际对应的数字(Dual tone multi-frequency signal, the audio signal is determined based on the actual input of the corresponding number)

计算7个Hu不变矩，使用于图像处理中的目标识别(Calculate seven Hu invariant moments used in image processing, target recognition)

在Juan Cardelino发布的FMM(fast marching methos)2维程序基础上改写的3维程序。并改写成适合复杂速度模型，可用于地震旅行时计算。大模型3d算法在matlab下计算速度较慢，根据源码中的注释很容易改写成c程序。(3D FMM program revised from Juan Cardelino s 2D version. The program can calculate the seismic traveltimes in 3D complex model)
