相场法模拟晶粒,有关相场的matlab程序，有相场法fortran源代码 (Matlab program on phase field)(grain evalution based on phase field method)

使用Fortran涡度、散度、涡度平流、温度平流计算代码(Using Fortran vorticity, divergence, vorticity advection, temperature advection calculation code.)

说明：  一个简单的CZT chirp-Z变换例程(a simple example of CZT)

fractal compression using wavelet

说明：  可以进行平面拟合，基于matlab语言，简单易懂(It can be used for plane fitting. It is simple and easy to understand based on MATLAB language.)

The following is an example of how Microsoft Solver Foundation can be used to solve a constraint satisfaction problem (CSP) like generating a typical Sudoku problem. Sudoku http://www.codeproject.com/Articles/419389/Sudoku-using-Microsoft-solver-foundation In this article I do not attempt to explain everything there is to know about constraint satisfaction problems, but I will go over the concepts in the hope that even if you have never heard of CSP you will still get the idea.

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.

快速排序法和堆排序法Fortran90程序，其中快速排序法使用到了递归过程，因此对于堆栈要求较高(both Quicksort and Heapsort program are used for sort array. Note that a recursion process is used in Quicksort program, Thus it need require a relative high stack size.)

比较完善的面向对象的有限元程序代码，适用于编写大型程序的学习(typical C++ code for OOFEM)
