计算圆阵方向图，可任意设置阵元个数和信号频率；并汇出三维图、二维方向图以及等高线图(Calculating circular array pattern can be arbitrarily set the number of array elements and signal frequency and export three-dimensional map, two-dimensional pattern and contour plots)

This piece of code can be used to import text file data of the signature samples, and pre-process them.

Used to annotate a method parameter to indicate that this method will close the resource.
