这是一个三次样条插值函数实现的C代码。如果插值点需要改变，可以在程序中改定。(This is a cubic spline interpolation function of the realization of the C code. If interpolation points need to change, the procedures will change.)

本程序在matlab中运行。 Generate_SystemMatrix是一个计算OSEM，MLEM迭代图像算法中系统矩阵的函数，其用法Generate_SystemMatrix（pixel），为所要重建图像的大小，一般为64,128,256，pixel也大运算越慢。 里面的diedai-test文件是一个简单的MLEM重建算法，其中要加载SystemMatrix矩阵就是Generate_SystemMatrix(128)的结果，注意如果要运行diedai-test，生成的系统矩阵名要保存为SystemMatrix，否则出错。 testsino是一个正弦图实例，就是MLEM算法中的投影矩阵，机算是数据。(This program is run in matlab. The Generate_SystemMatrix is ​ ​ a calculation of the OSEM, a function of the system matrix MLEM iterative image algorithm, its use Generate_SystemMatrix (pixel) to rebuild the image size, usually 64,128,256, pixel also large computing slower.

用fortran写的牛拉潮流计算程序，实验中的结果，比较简单，仅供参考(fortran write with ox-drawn flow calculation procedure, the results of experiments, relatively simple, for information purposes only)

计算声子晶体固-液和固-气体系，和实验测试吻合，很适应(Suitable for computing phononic crystal solid-liquid and solid and gas, and experimental agreement )

说明：  用em算法估计高斯混合模型参数，matlab代码(Estimation of Gaussian mixture model parameters by EM algorithm)

说明：  用于石油地震资料数字处理，包括 地震偏移（二维或三维）、滤波程序、重采样、具有很广的应用前景，还可以移植到其他的工程领域。(oil for digital processing seismic data, including seismic migration (2D or 3D), filtering procedures, re-sampling, have a very broad application prospects, but also can be transferred to other engineering fields.)

矩阵计算英文版第4版，经典，经典，很不错！！！！！请下载！！！！！！(Matrix Computing English Version 4, classic, classic, very good!!!! Please download!!!!!!)

本程序是用节点导纳矩阵计算三相短路电流 输入数据--形成节点阻抗矩阵--选择故障点---计算短路电流----计算个节点电压---计算指定支路的电流(this procedure is used node admittance matrix calculation of three-phase short-circuit current input data-- forming node impedance matrix-- election Optional fault--- calculation of short-circuit current-voltage computing nodes designated calculated slip road--- Electricity)
