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： L3GJq{t  
Warning: in run: there was no simulation data. The simulation failed to run. \ yOZ&qU  
Error:  Can not find result 'E' in the result provider 'field' 4z*_,@OA  
代码如下： X*JD  
radius = 1e-6*[0.25,0.75]; {``}TsN  
for (i=1:length(radius)) { Tb)x8-0  
    setnamed("::model","radius",radius(i)); 4`UT_LcI  
    run; 8 6+>|  
    E = getresult("field","E"); 5o3_x ~e  
    x = E.x; 0iL8i#y*  
    z = E.z; E{6}'FG+A  
    Ex = E.Ex; +[qkG. O  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); gK<-*v
