梯度下降法优化函数，包括回溯搜索法和精确直线法(Gradient descent method to optimize the function, including backtracking search method and precise line method)

用matlab编写的视频目标跟踪程序，可以跟踪路上的行人(Prepared using matlab video target tracking program, you can track the path of pedestrian)

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)

已知离散的坐标数据，利用这些坐标点进行椭圆拟合的程序(Known coordinates of discrete data points to use these coordinates ellipse fitting procedure)

In this section, the PAPR performance of the proposed algorithms is shown. To evaluate the PAPR performance, the CCDF is employed. The specification detail of simulation parameters is given in TABLE I. In Fig. 5 is shown the PAPR with a PTS method (U = 8) and conventional PTS (U = 4) are improved 4.3 dB and 2.6 dB from ordinary MIMO-OFDM signal when CCDF = 10− 4 respectively and Fig. 6 is shown the PAPR with an optimal PTS method in case of 128 subcarriers.
