调用数值求根函数来求解平面光波导中的导模(Can be solved by numerical o root function called planar optical waveguide in the mould)

在matlab中用数值法求解一阶贝塞尔函数的前10个零点，并作出一阶贝塞尔函数曲线，并在曲线上标注出其零点。(In MATLAB, the first 10 zeros of the first order Bessel function are solved by numerical method, and the first order Bessel function curve is made, and the zero point is marked on the curve.)
