摘要
在理论物理研究中导出的超越方程,可以借助于Matlab软件进行数值解,并可以控制解析解的精度。以炮弹的发射速度-发射角之间和平板光波导导波模式的超越方程为例进行研究,结果表明:理论物理超越方程可以通过设定参数和选取Matlab适当命令编写程序进行运算而得到最佳的精确解,这在工程科学、材料科学、光电子等多个领域具有一定的理论指导作用和实际应用价值。
The numerical solution of the transcendental equation in the theoretical physics research can be derived with the help of the Matlab software, and the accuracy of the solution can be controlled. Take the transcendental equation of the launch speed-emission angle of shell and the planar optical waveguide guided wave mode for an example, it proves that the transcendental equation in theoretical physics can get the best solutions by setting parameters and selecting the Matlab appropriate command program with the help of computer, which has much theoretical guidance and practical value in engineering science, materials science, optoelectronics and other fields.
