稀疏阵的方向图仿真，给出了不同条件下的稀疏阵列的方向图(This is the simulate about sparse array ,different conditions have been taken into account )

这个程序实现了Levenberg Marquardt Fletcher(LMF)算法，并用于非线性最小二乘的计算。用于在一个非线性多项式组成的矛盾/超定方程组中，找到最优的解。(This program implements the Levenberg Marquardt Fletcher (LMF) algorithm, and used nonlinear least squares calculations. Formed in a non-linear polynomial for the conflict/overdetermined equations, find the optimal solution.)

有限元方法分析典型结构,采用六节点三角形单元(This programming give an order 6 triangulation, an abstract list of sets of six nodes. The vertices are listed clockwise, then the midside nodes.)

说明：  利用自相关函数估计基音周期，函数jiyinzhouqi，输入参数是分析语音文件名和帧移，帧移在5~10ms(use of the correlation function is estimated Pitch, jiyinzhouqi function, input parameters to analyze voice file names and frame shift, frame shift in the 5-10ms)

二维码扫描应用demo，精选ios编程学习源码，很好的参考资料。(Two dimensional bar code scanning application demo, select learning IOS programming source code, a good reference.)

这段代码主要用于工程中的结构有限元设计，依次从代码中很容易求解出结构所划分的节点数，单元数以及荷载等。(This code is mainly used for finite element in structural engineering design, are easily solved by the number of nodes in the structure of the number of units, and load.)

比较齐全的hht算法的程序，可以进行谱峭度分析，选取峭度最大的分量，求其包络谱，能够明显看出特征频率，比较实用。(A more complete algorithm of HHT algorithm can carry out spectral kurtosis analysis, select the largest component of kurtosis, and find its envelope spectrum, which can clearly see the characteristic frequency, and is more practical.)
