用途：用向量(稀疏存储)形式的Gauss-Seidel迭代解线性方程组Ax=b ％ 格式: x=spgs(A,b，x0,e,N),A为系数矩阵，b为右端向量，x返回解向量。 ％ x0为初值向量(默认原点)，e为精度(默认1e-4),设置迭代次数上限以防发散(默 ％ 认500)。 -purposes : with Vector (sparse storage) form of Gauss- Seidel iterative solution of linear equations Ax = b% Format : spgs x = (A, b, x0, e, N), A coefficient matrix, b subguadratic vector, returning x vector. X0% for initial vector (the default origin), e-precision (default 1e-4), iteration ceiling set to prevent divergence (mime identified 500%).

截图软件，有快捷键功能，可以调用系统画图和照片查看器进行编辑和查看。全屏截图，选择截图，快捷键用钩子实现，对于初学编程的人比较有用。Screenshot of the software, there are shortcut keys function, you can call the system drawing and photo viewer for editing and viewing. Full-screen screenshot, select shots, shortcuts hook used to achieve more useful for the novice programmer person.

在Windows大行其道的今天，windows界面程序受到广大用户的欢迎。对这些程序的 操作不外乎两种，键盘输入控制和鼠标输入控制。有时，对于繁杂的，或重复性的输入 操作，我们能否通过编制程序来代替手工输入，而用程序来模拟键盘及鼠标的输入呢？ 答案是肯定的。这里主要是通过两个Windows API函数来实现的。 -Windows popular in today, windows interface procedures by the majority of users. The operation of these procedures only two input control keyboard and mouse input control. Sometimes, for complex or repetitive input operations, our ability to process through the development to replace the manual input, and using procedures to simulate the keyboard and mouse input it? The answer is yes. Here mainly through the two Windows API function to be achieved.
