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 vibrati
