计算矩形平板的声辐射特性，该平板为有障板的矩形薄板，考虑板在水中的声振耦合问题(CALCULATION OF ACOUSTIC RADIATION CHARACTERISTICS OF RECTANGULAR PLATES)

sandberg著作中实例的MATLAB实现，已对其进行详细的中文注释，对于声振耦合有限元法的初学者大有裨益。(The matlab implementation of the example in Sandberg's works has been annotated in detail in Chinese, which is of great benefit to the beginners of acoustic vibration coupling finite element met
