输入单元节点坐标及材料参数，输出单元刚度矩阵，用4节点平面四边形等参单元计算分析平面应力问题。(Nodal coordinate input unit and material parameters, the output element stiffness matrix, using a 4-node plane quadrilateral isoparametric plane stress calculation and analysis unit.)

演示了mallat算法的实现过程，包括分解与重构，原始波形用的是两个不同频率的正弦函数(Mallat algorithm demonstrated the realization of the process, including the decomposition and reconstruction, with the original waveform are two different frequency sine function)

说明：  控制受控电流源模拟光伏电池PV、IV外特性(Controlled current source analog control external characteristics of photovoltaic cells)

本程序是计算深海远场情况下的声源定位，首先要编译海洋环境文件（包含阵元信息），利用Krakren程序计算本征函数和本征模态，再利用本程序的子程序计算拷贝向量，然后合成声源信号，最后根据匹配场的程序进行匹配定位，由于数据量比较大，计算区域如果选的比较大的话，计算时间就比较长，酌情选择。(This procedure is to calculate the far-field sound source localization in case of deep sea, we must first compile the marine environment file (containing the array element information), use Krakren program to calculate the intrinsic function and the intrinsic mode, and then use a subroutine to copy the program to calculate the vector then synthesized excitation signal, the final match to locate the matching field program, because a large amount of data to calculate the area if the election is relatively large, the calculation time is relatively long, discretionary selection.)
