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： M0o=bYI  
Warning: in run: there was no simulation data. The simulation failed to run. l1`Zp9I  
Error:  Can not find result 'E' in the result provider 'field' G~)jk+Qq  
代码如下： ><OdHRh@#  
radius = 1e-6*[0.25,0.75]; aq"E@fb  
for (i=1:length(radius)) { :YjOv  
    setnamed("::model","radius",radius(i)); 4,f[D9|:  
    run; )Y~q6D K  
    E = getresult("field","E"); S}e*~^1J  
    x = E.x; Bt,qG1>$-  
    z = E.z; [$3Zid  
    Ex = E.Ex; If6wkY6sR  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); +`f gn9p
