基于混合高斯模型的多目标跟踪算法，对背景图像建立混合高斯模型，实时更新高斯模型，达到更新背景的目的。(Gaussian mixture model-based multi-target tracking algorithm, Gaussian mixture model to establish the background image, real-time updates Gaussian model, to achieve the purpose of updating the background.)

matlab三相不平衡系统潮流计算程序,三相不平衡系统，采用前推回代计算方法(matlab Unbalanced flow calculation program, three-phase unbalanced system, using forward and backward substitution calculation method)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(Cochlear substantially equivalent to a filter set, cochlear filter is used on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )

说明：  编程计算图形的面积。程序可以计算圆形，长方形，正方形的面积，运行时先提示用户选择图形的类型，然后，对圆形要求用户输入半径值，对长方形要求用户输入长和宽的值，对正方形要求用户输入边长得值，计算出面积的值后将其显示出来。(Calculate the area of graphics programming. Program can calculate the round, rectangular, square area, run-time prompts the user to first select the type of graph, and then the radius of the circle requires the user to input the value of the rectangle requires the user to input the length and width values, requires the user to input side of the square grow the value to calculate the value of the area after the show.)
