线性鉴别分析方法，数据降维，图像处理，模式识别(LDA)

该程序是基于时间延迟求和的波束成形算法的实现，根据是结果来看有很好的效果(The program is based on the sum of the time delay beamforming algorithm, based on results, there is a good effect)

此代码利用高斯牛顿迭代法，对非线性函数进行参数辨识。可以对传递函数通过阶跃响应实验得到的数据进行迭代获得传递函数的参数(The code uses the Gauss-Newton iteration method to identify the parameters of the non-linear function. The parameters of the transfer function can be obtained by iterating the data obtained from the step response experiment of the transfer function.)

说明：  2维高斯拟合 实验过程中用到的 主要是对自己的实验数据的分布频数进行一个二维的高斯拟合来方便可视化实验数据的分布(In the process of 2-D Gaussian fitting experiment, we mainly use a 2-D Gaussian fitting for the distribution frequency of our experimental data to facilitate the visualization of the distribution of experimental data)
