利用matlab软件建立模型，利用ARMA模型对数据进行预测(Using matlab software to model the data using the ARMA model prediction)

说明：  逆变器 背靠背变换器的 PI控制 电气模型(CONVERTER BACK TO BACK)

说明：  自己做的两相混合式步进电机细分驱动控制，已经闭环成功，效果还不错(Self-made two-phase hybrid stepping motor subdivision drive control, has been closed-loop success, the effect is good.)

很简单易懂的卡尔曼滤波算法，希望能帮助到初学者(kalman filter)

我不太会用matlab，这就是一个用过来实现DPC的算法(Implementation of DPC)

指纹预处理程序，MATLAB编的，可以运行(Fingerprint preprocessing procedure, MATLAB series, you can run)

提取语音信号的基音周期的matlab程序(Extract the pitch period of the voice signal matlab program)

无约束一维极值问题，进退法，黄金分割法、奜波那契法，牛顿法，割线法，goldstein法，wolfe-powell 算法matlab源代码(Unconstrained a d extremum problems, in a method, the golden section method, wave that contract law, Newton method, secant line rule, goldstein method, Wolfe-Powell algorithm matlab source code )

互信息相关配准的matlab程序，能够对不同源图像进行相关匹配(Mutual information related to the registration of the matlab program, capable of matching different sources related images)

修改自pudn的fm_gui_v2.基于相位相关方法（傅里叶变化），可有效实现任意大小两图的位移、尺度变化、旋转量，并输出拼接结果(Modified pudn of fm_gui_v2. Based on phase correlation method (Fourier transform), which can effectively achieve the displacement of any size, the two figures, the scale changes, the amount of rotation, and outputs the result stitching)
