GM11.m是基于灰色系統理論的GM(1,1)模型編寫的，開發軟件為matlab(2010b)版。應用范圍為所有符合GM(1,1)模型的數據。 具體使用方法：x0為原始數據，需由用戶自行輸入，輸入方式可選擇調用txt格式或excel文件格式等。模型中的N值為數列的預測步數， 也由用戶根據實際情況輸入。 文件已保存成.m文件，故可作為matlab的function直接調用，用戶只需使用[yc0]=gm11(x0)語句即可實現調用。

Boost C++ Libraries Free peer-reviewed portable C++ source libraries Boost C++ Libraries 基本上是一個免費的 C++ 的跨平臺函式庫集合，基本上應該可以把它視為 C++ STL 的功能再延伸；他最大的特色在於他是一個經過「同行評審」（peer review，可參考維基百科）、開放原始碼的函式庫，而且有許多 Boost 的函式庫是由 C++ 標準委員會的人開發的，同時部分函式庫的功能也已經成為 C++ TR1 (Technical Report 1，參考維基百科)、TR2、或是 C++ 0x 的標準了。 它的官方網站是：http://www.boost.org/，包含了 104 個不同的 library；由於他提供的函式庫非常地多，的內容也非常地多元，根據官方的分類，大致上可以分為下面這二十類： 字串和文字處理（String and text processing） 容器（Containers） Iterators 演算法（Algorithms） Function objects and higher-order programming 泛型（Generic Programming） Template Metaprogramming Preprocessor Metaprogramming Concurrent Programming 數學與數字（Math and numerics） 正確性與測試（Correctness and testing） 資料結構（Data structures） 影像處理（Image processing） 輸入、輸出（Input/Output） Inter-language support 記憶體（Memory） 語法分析（Parsing） 程式介面（Programming Interfaces） 其他雜項 Broken compiler workarounds 其中每一個分類，又都包含了一個或多個函式庫，可以說是功能相當豐富。

matlab有限元網格劃分程序 DistMesh is a simple MATLAB code for generation of unstructured triangular and tetrahedral meshes. It was developed by Per-Olof Persson (now at UC Berkeley) and Gilbert Strang in the Department of Mathematics at MIT. A detailed description of the program is provided in our SIAM Review paper, see documentation below. One reason that the code is short and simple is that the geometries are specified by Signed Distance Functions. These give the shortest distance from any point in space to the boundary of the domain. The sign is negative inside the region and positive outside. A simple example is the unit circle in 2-D, which has the distance function d=r-1, where r is the distance from the origin. For more complicated geometries the distance function can be computed by interpolation between values on a grid, a common representation for level set methods. For the actual mesh generation, DistMesh uses the Delaunay triangulation routine in MATLAB and tries to optimize the node locations by a force-based smoothing procedure. The topology is regularly updated by Delaunay. The boundary points are only allowed to move tangentially to the boundary by projections using the distance function. This iterative procedure typically results in very well-shaped meshes. Our aim with this code is simplicity, so that everyone can understand the code and modify it according to their needs. The code is not entirely robust (that is, it might not terminate and return a well-shaped mesh), and it is relatively slow. However, our current research shows that these issues can be resolved in an optimized C++ code, and we believe our simple MATLAB code is important for demonstration of the underlying principles. To use the code, simply download it from below and run it from MATLAB. For a quick demonstration, type "meshdemo2d" or "meshdemond". For more details see the documentation.

Use the fast Fourier transform function fft to analyse following signal. Plot the original signal, and the magnitude of its spectrum linearly and logarithmically. Apply Hamming window to reduce the leakage. . The hamming window can be coded in Matlab as for n=1:N hamming(n)=0.54+0.46*cos((2*n-N+1)*pi/N); end; where N is the data length in the FFT.
