基带通信系统设计，用MATLAB软件编程实现(communication system design)

implements the secant method for solving an equation f(x) = 0.

说明：   改进的牛顿法求解： 方程的构造方法:给出[0,1]区间上的随机数(服从均匀分布)作为方程的根p*. 设你的班级数为a3,学号的后两位数分别为a2与a1,从而得到你的三次方程 例如:你的31班的12号,则你的方程是21x3+60x2+2x+a0=0的形式. 方程中的系数a0由你得到的根p*来确定. (improve Newton's method : Construction of the equation : given interval [0,1] on the random number (subject to uniform distribution) as the root equation p*. set up your classes at a3, after learning of the double-digit for a1 and a2, so you get the three equations for example : Your 31 classes on the 12th, then your equation is 21x3 60x2 2x a0 = 0 forms. the equation coefficients a0 you get from the root of p* to determine.)

this is ME assignment on speech with the matlab code and results with proper results and documentation.

运用高斯混合模型，识别车辆，分割车辆，检测车流量，运算很快，效果不错(Using the gaussian mixture model, identification of vehicles, vehicle segmentation, detection and traffic operation soon, effect is good)

CVT_METRIC is a MATLAB program which computes a CVT (Centroidal Voronoi Tessellation) calculation under a spatially varying metric. d(a,b) = ( a - b ) * A * ( a - b )
