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： eR>oq,  
Warning: in run: there was no simulation data. The simulation failed to run. B+`g>h
 
Error:  Can not find result 'E' in the result provider 'field' 'g\4O3&_  
代码如下： _[BP0\dPW  
radius = 1e-6*[0.25,0.75]; h*\%
vr  
for (i=1:length(radius)) { RRJ%:5&  
    setnamed("::model","radius",radius(i)); jP.
dDYc  
    run; "tK=+f`NM  
    E = getresult("field","E"); %|oym.-I6  
    x = E.x; f o3}W^0  
    z = E.z; gSj,E8-g  
    Ex = E.Ex; P%n>Tg80M  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); $`8wJf9@w
