matlab常微分方程

小波包分析提取振动信号中的特征频率，调试通过可以使用，自己编的5种调制信号。( Wavelet packet analysis to extract vibration signal characteristic frequency, Debugging can be used, Own five modulation signal.)

C语言实现大数的加法减法以及乘法,水平限于仅仅大学生水平学习使用。(Use C language to achieve that addition, subtraction, and multiplication of a big intger.)

说明：  设计一个函数，其功能是同时求得长度为20的整型数组所有元素中的最大值、最小值和平均值。并用相应的主函数对其进行测试，测试数组可以用随机数填充或者自行定义数据。(The design of a function, its function is to obtain the length of the maximum, minimum and average 20 integer array element. And its main function testing, the test array can be populated with a random number or define your own data.)
