请问大家下面这段代码中setnamed命令中的几个分别代表什么意思啊？脚本运行的时候发现半径为0.25μm时可以正常运行，但为0.75μm的时候出现一个错误： @<3E`j'p  
Warning: in run: there was no simulation data. The simulation failed to run. Mq#m
;v$E  
Error:  Can not find result 'E' in the result provider 'field' gzlxkv-F{  
代码如下： Ell14Iki  
radius = 1e-6*[0.25,0.75]; m62Zta  
for (i=1:length(radius)) { 9 Jw,ls  
    setnamed("::model","radius",radius(i)); =@ acg0  
    run; e]nP

    E = getresult("field","E"); +.&P$`;TZj  
    x = E.x; vp2w^/])u  
    z = E.z; De>e`./56  
    Ex = E.Ex; X&HYWH'@,  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); ZR -RzT1
