中文说明：通过虚拟阵元进行DOA估计，计算两个矩阵之间的欧氏距离，主要为数据分析和统计，意信号卷积的运算,并且绘制图象，调试通过可以使用，从先验概率中采样，计算权重。
English Description：
The virtual array for DOA estimation and calculation of the Euclidean distance between two matrices, mainly for data analysis and statistics, signal convolution operation and draw images, through the debugger can be used, sampled from the prior probability to compute the weights.
