主要介绍了怎样创建三管相贯的几何体。在生成网格之前，对此三管几何体进行了分解，形成四部分：三根单管和位于相贯处的楔形体（八分之一球体）。然后，对这些分体分别运用GAMBIT中的Cooper和Tet Primitive网格化方法进行了网格划分。-Introduces how to create three intersecting geometry. Before generating the grid, this three geometry was decomposed to form fou

这是个用matlab实现的球形译码算法 大家可以参考一下 希望有用-This is achieved using matlab sphere decoding algorithm we can refer to I hope useful

Firstly, this study does research on the quantitative uation of the acoustic performance of the planar ultrasonic array sensors. Sparse signal decomposition theory is then applied to find three different directions of arrival (DOAs) of the signal
