Dandn文件给出了输入参数的名称及格式 即在调用prim前先输入邻接矩阵D和节点个数n输入prim得到两行的矩阵T,将上下两行数字对应的节点相连即可(Dandn file name given input parameters and format that is called prim before Input adjacency matrix D and node numbers n input prim are two lines of the matrix T, the number of up and down two lines can be connected to the corresponding node)

计算曲面换能器空间各点随时间变化的声场强度，采用的是时间差分法。精度高。(Transducer surface computing space changes over time, each point field intensity, using the time difference. High accuracy.)

主成分分析(PCA)是一个数学的过程,它使用一个正交变换转换成一组观测到的可能相关的因素形成一套价值观的独立变量称为主成分。主成分的数量小于或等于原始变量的数目 (Principal component analysis (PCA) is a mathematical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of uncorrelated variables called principal components. The number of principal components is less than or equal to the number of original variables)

用于对大规模文件进行操作，但对文件内容有很大的局限性，仅供参考思路(For large-scale file has many limitations, but the contents of the file are for reference only ideas)

CVT_METRIC is a MATLAB program which computes a CVT (Centroidal Voronoi Tessellation) calculation under a spatially varying metric. d(a,b) = ( a - b ) * A * ( a - b )

说明：  基于MATLAB语言的RFS过滤/跟踪代码(MATLA random finite set filtering/tracking codes)

matlab edge preserving filter

说明：  这是旅行商问题的完全压缩包，很好用。算法的计算速度很快，而且收敛效果很好的。(This is the traveling salesman problem completely compressed package, very handy. Algorithm, and the calculation speed quickly effect is very good convergence. )

matlab源程序，包括各种MATLAB的小程序源码(Matlab source, including small programs MATLAB source!)
