使用差分法解一类Bessel方程在不同边界条件下的离散解(the use of differential method for a type Bessel equation in different boundary conditions of the Discrete Solutions)

这是关于MUSIC算法的文档。希望对初学空间谱估计的人有帮助！(This is the document of MUSIC algorithm. I hope it can help beginners of spatial spectrum estimation. )

基于OC算法的连续体动力学机构拓扑优化设计代码，值得下载收藏(The code of topology optimization design of continuum dynamics mechanism based on OC algorithm is worth downloading and collecting.)

这是我强烈推荐的一本书，它是基于开源软件做的类似于matlab的一个工具，功能非常的强大，建议在校学生好好学习这门课，对于以后的应用会有很大的帮助(python)
