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： Y%<y`]I  
Warning: in run: there was no simulation data. The simulation failed to run. %oPW`r  
Error:  Can not find result 'E' in the result provider 'field' Bgb~Tz'  
代码如下： U9w0kcUw#J  
radius = 1e-6*[0.25,0.75]; 6ub-NtVu  
for (i=1:length(radius)) { s D
q{h  
    setnamed("::model","radius",radius(i)); {A!1s;  
    run; hr@c7/L  
    E = getresult("field","E"); ~,#zdm1r@  
    x = E.x; $sF'Sr{)y  
    z = E.z; ogD 8qrZ6J  
    Ex = E.Ex; pJ8;7u  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); &1
