FDTD导出matlab中画的矢量图为什么有差别

      fig1_FDTD;   fig2_matlab;

      请问如何才能使得matlab中绘制的图和fdtd中一样?

      看到您在别的帖子下的回复,于是进行归一化处理,但是归一化后在matlab中绘制出的矢量图

      貌似产生了错误的变化

      你使用

      相当于做了归化,应该不需要归化。

      此外,E分量都是复数,其平方还是复数,只有其绝对值才是实数,请考虑是否需要某种归化。

      还有,Matlab使用的是均匀网格,而FDTD一般是非均匀网格,在将数据转给Matlab之前需要先插值为均匀网格:
