sift算法page，详细论述了sift算法的基本过程(sift algorithm page, sift algorithm discussed in detail the basic processes)

MATLAB SIMULINK设计的电液伺服控制仿真系统(MATLAB SIMULINK simulation system designed electro-hydraulic servo control)

利用系统辨识的方法，根据传感器实际输出和理想等效系统的输出，来辨识补偿环节的模型(use of the system identification method, in accordance with the actual sensor output and ideal equivalent system output Identification link compensation to the model)

用早迟门实现定时同步！实现通信系统仿真，(Achieved with the early-late gate timing synchronization! Communication System Simulation,)

实现图像的对数极坐标变换，具有旋转不变性，可用于数字水印的抗几何攻击(achieving the right number of images Polar transform, with a rotating invariance, the digital watermark can be used against geometric attack)

MATLAB提供了各种曲线拟合方法，例如：Exponential, Fourier, Gaussing, Interpolant, Polynomial, Power, Rational, Smoothing Spline, Sum of Functions, Weibull等，当然，也可以使用 Custom Equations. cftool不仅可以绘制拟合后的曲线、给出拟合参数，还能给出拟合好坏的评价参数(Goodness of fit)如SSE, R-square, RMSE等数据，非常好用。但是如果我们已经确定了拟合的方法，只需要对数据进行计算，那么这种GUI的操作方式就不太适合了，比如在m文件中就不方便直接调用cftool。 (matlab has given a lot of method for curve combine ,we will give a new method and provide a matlab code.)

here i have provided a matlab code in which we have the gold price of laast 4 yrs.we have predicted and showed it using a matlab code.
