MATLAB调用FEKO计算电场，可更改参数，读取计算结果-MATLAB to call FEKO to calculate the electric field.It can change the parameters and read the calculated results

可利用feko得到回波或根据公式构造回波，基于字典缩放的属性散射中心的参数提取，并重构回波(The echo can be obtained by using FEKO, or the echo can be constructed according to the formula. The parameters of the scattering center of the dictionary are extracted based on the dictionary scaling and
