将系数矩阵A转变成等价两个矩阵L和U的乘积 ，其中L和U分别是下三角和上三角矩阵。当A的所有顺序主子式都不为0时，矩阵A可以唯一的分解为A=LU。其中L是单位下三角矩阵，U是上三角矩阵。 (The coefficient matrix A into two matrices L and U is equivalent to the product, where L and U are lower triangular and upper triangular matrix. When A master style is not all the sequence is 0, the matrix A can only be decomposed into A = LU. Where L is unit lower triangular matrix, U is upper triangular matrix.)

This is the machine-generated representation of a Handle Graphics object and its children. Note that handle values may change when these objects are re-created. This may cause problems with any callbacks written to depend on the value of the handle at the time the object was saved.(This is the machine-generated representa tion of a Handle Graphics object and its childre n. Note that handle values may change when these objects are re-created. This may cause problem s with any callbacks written to depend on the val ue of the handle at the time the object was saved.)

在风力发电的模拟系统中,风速模拟是一个重要的环节,正确的风速模型不仅能够很好的 反应实际风速变化情况,而且能够给风力发电系统研究提供正确的源参数。本文用 Matlab/Simulink建立了风速组合数学模型,该模型将风速分为基本风速、阵风、渐变风速和噪声风 速4部分,仿真结果表明该模型能够理想的反应实际风速 (Wind speed simulation is an important part in the simulation of wind power generation system, wind speed model can well reflect the actual wind speed changes, but also to provide the correct source parameters to the wind power system studies. Wind speed combination of mathematical model using Matlab/Simulink, the model will be divided into basic wind speed, gust, gradient, wind speed and noise wind wind simulation results show that the model can be the ideal response to the actual wind)

用户界面（或接口）是指：人与机器（或程序）之间交互作用的工具和方法。如键盘、 鼠标、跟踪球、话筒都可成为与计算机交换信息的接口。 图形用户界面（Graphical User Interfaces ，GUI）则是由窗口、光标、按键、菜单、文 字说明等对象（Objects）构成的一个用户界面 (User interface (or interface) refers to: Human and machine (or process) the interaction between the tools and methods. Such as keyboard, mouse, track ball, microphone and computer can become the interface to exchange information. Graphical user interface (Graphical User Interfaces, GUI) is by the window, the cursor, buttons, menus, text and other objects (Objects) consisting of a user interface)
