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： 6l]jmj)/  
Warning: in run: there was no simulation data. The simulation failed to run. o5LyBUJ  
Error:  Can not find result 'E' in the result provider 'field' /|Z_Dy  
代码如下： znnnqR0us  
radius = 1e-6*[0.25,0.75]; g]&7c:/  
for (i=1:length(radius)) { .3>`yL  
    setnamed("::model","radius",radius(i)); uJ-Q]yQ  
    run; e_=TkG1E6  
    E = getresult("field","E"); ;$,b w5  
    x = E.x; ^G(U@-0..  
    z = E.z; M5 \flE2  
    Ex = E.Ex; |ht:_l 8  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); R&.
