For a general variable cross-section beam, it is very difficult to obtain an analytical solution. At present, the numerical method is still generally used for solving. In various numerical methods, the transfer matrix method has its unique advantages. The transfer matrix method is simple to calculate, saves memory, and can be implemented on small computers as ’‘-‘]. This article applies the transfer
