基于Matlab的程序，复化梯形公式求积分的算法(Matlab-based procedures, rehabilitation of trapezoidal formula for integration algorithm)

说明：  给定随机过程，用对偶变量法模拟标的资产的价格路径, 提高一倍速度，并减小一半的标准差(Given random process, with dual variable method for modeling the underlying asset price path, double speed, and reduce the standard deviation of half)

程序先进行卷积编码，然后进行viterbi译码，程序有纠错功能，中间出现误码，程序解码时会自动纠正(Convolution coding program first and then viterbi decoding program has error correction, the error appears in the middle, when the program will automatically correct decoding)

说明：  矢量控制是目前交流电机的先进控制方式，一般将含有矢量变换的交流电机控制都称 之为矢量控制，实际上只有建立在等效直流机模型上，并按转子磁场准确定向的控制，电机才能获得最优的动态性能。 矢量控制的基本思路是以产生相同的旋转磁动势为准则，将异步电机在静止三相坐标系上的定子交流电流通过坐标变换等效成同步旋转坐标系上的直流电流，分别加以控制，以达到直流电机的控制效果。(Vector control is an advanced control method of AC motor at present. Generally, vector control is called vector control. In fact, only based on the equivalent DC motor model and accurately oriented control according to the rotor magnetic field, can the motor obtain the optimal dynamic performance. The basic idea of vector control is to generate the same rotating magnetomotive force as the criterion. The stator AC current of asynchronous motor in the static three-phase coordinate system is converted into DC current in the synchronous rotating coordinate system by coordinate transformation, and then controlled separately to achieve the control effect of DC motor.)
