数值计算中SOR迭代法的Matlab程序(numerical calculation SOR iteration of the Matlab program)

说明：  实现CDMA的rake接收仿真，检测使用PDI检测(CDMA rake receiver to achieve the simulation, testing using the PDI test)

利用T-S方法控制单倒立摆，建立了多个模糊规则。(Sugeno type fuzzy control for single inverted pendulum)

说明：  毕业设计时的ofdm的仿真程序，做的还算可以，顺利毕业了。(graduation OFDM design of the simulation program, can be done fairly smoothly graduated.)

This matlab code implements the region split and merge segmentation of an image

MATLAB 牛顿下山法的一个小程序，原理就不详细说了。因牛顿迭代法受初值选取的限制，为防止迭代发散，对迭代过程再附加一项要求:|f(x(k+1))|<|f(x(k))|,将牛顿法迭代的结果:x(k+1) =x(k)-f(x(k))/f (x(k))和前一近似值x(k)适当加权平均做为新的改进值:x(k+1)=u*x(k+1) +(1-u)*x(k),其中u(0<> 迭代时u取1开始，逐次减半计算，直至附加要求符合为止。实例计算中x(k)=x(0)不变，只更新u和x(k+1)，直至:|f(x(k+1))|<|f(x(k))|（即|f(x(1))|<|f(x(0))|)，然后更新下山因子为u=1,继续以牛顿法迭代。(MATLAB Newton-down a small program, the principle is not explained in detail. Newton iteration by the initial value of the selected limit, in order to prevent additional iterative divergence, the iterative process a request: | f (x (k+1)) | < | f (x (k)) | Newton iteration Results: x (k+1) ' = X (k)-f (x (k))/f' (x (k)) and a previous approximation x (k), appropriately weighted average as a new improved value: x (k+1 ) = u* x (k+1) ' + (1-u)* x (k), where u (0 < u> iteration take successive calculated at 50 until the additional requirements found so far. examples of calculation of X ( k) = x (0) unchanged profile u and x (k+1, hungry) until: | f (x (k+1)) | < | f (x (k)) | (i.e. | f (x (1)) | < | f (x (0)) |), then profile downhill factor for u = 1, to continue to Newton iteration.)

在同一坐标内，分别用不同线型和颜色绘制曲线y1=0.2e-0.5xcos(4πx) 和y2=2e-0.5xcos(πx)，标记两曲线交叉点。( In the identical coordinates, separately uses different linear and color curve y1=0.2e-0.5xcos (4 pi x) and y2=2e-0.5xcos (pi x), marks two curves intersections. )
