说明：  计算金属圆盘随角度变化的RCS 并输出函数图(function fig = rcs_circ_plate_driver() % This is the machine-generated representation of a Handle Graphics object % and its children. Note that handle values may change when these objects % are re-created. This may cause problems with any callbacks written to % depend on the value of the handle at the time the object was saved. % This problem is solved by saving the output as a FIG-file. % % To reopen this object, just type the name of the M-file at the MATLAB % prompt. The M-file and its associated MAT-file must be on your path. % % NOTE: certain newer features in MATLAB may not have been saved in this % M-file due to limitations of this format, which has been superseded by % FIG-files. Figures which have been annotated using the plot editor tools % are incompatible with the M-file/MAT-file format, and should be saved as % FIG-files.)
