In numerical analysis, the secant method is a root-finding algorithm that uses a succession of roots of secant lines to better approximate a root of a function f.(The secant iteration to find the zero of some non-linear function converges to zero if appropriate starting values are chosen. Although the convergence rate is not as good as the one of the Newton method, it may sometimes converge when Newton fails. The funtion should be defined as an inline function and two starting values are required to start the iteration. Please enter help secant from the Matlab prompt for usage information and examples. )

DCT变换1、 提取彩色图像，将图像大小限制为512*512*3； 2、 提取彩色图像三个颜色分量的矩阵，每个矩阵单独处理； 3、 将矩阵分为8*8的块，做DCT变换； 4、 提取每个块的一部分DCT系数做IDCT变换，显示基本图像； 5、 再提取每个块的一部分DCT系数做DCT反变换，得到增强层1，与前一次得到的数据叠加，得到质量更好的图像。 (DCT transform)

利用目前风力机叶片设计普遍采用的优化设计方法Wilson设计A-法，通过MATLAB编程，开发了小型叶片气动设计的应用程序，并利用该程序设计了一台3kW小型水平轴风力机叶片。采{用MATLAB和ANSYS共同建立了风力机叶片三维有限元参数模型，MATLAB编制的建模程序提高了{初期设计效率，缩短了ANSYS分析前处理时间。在此基础上进行了叶片固有振动特性计算，分析了叶《片的振动特性及其与结构参数之间的关系，分析方法和结果对风电叶片的结构设计和动力分析有一定；的参考价值。(Advantage of the current design of wind turbine blades commonly used in optimal design method Wilson designed the A-Law, MATLAB programming, developed a small blade aerodynamic design application and use of the program designed a 3kW small horizontal axis wind turbine blades. Mining {using MATLAB and ANSYS common parameter model of wind turbine blades dimensional finite element modeling program MATLAB prepared the {initial design efficiency, shortening the ANSYS analysis of the pre-treatment time. On this basis, the natural vibration characteristics of leaves, the relationship between leaf on vibration characteristics and structural parameters, analytical methods and the results of analysis has some structural design of wind turbine blades and power reference value.)

A very interesting game to play amongst two players....Requires a lot of logic (Steps to follow -Execute game.m -hit start button -play and enjoy:) Rules to play -In their respective turns,each player will chose a cell to drop ur token ball in it(by clicking in a cell). -the selected cell cannot be already occupied by opponent s token ball. -when a cell has sufficient no of balls such that atleast one ball will shoot in every available direction,the balls will evacuate this cell and move in all available directions.Let s call this event explosion . -in an event of explosion,the balls released will occupy the cell they travel to. -in case the cell where a ball has come due to explosion of an adjacent cell already contains tokens of the opponent ,these tokens will get mutated to the type of ball coming in due to explosion. -If a cell receives more number of balls than required for explosion,the extra balls will be lost Aim to destroy all of the opponent s token balls. --------------------------------------------------------------------)
