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： U3}R^W~eb  
Warning: in run: there was no simulation data. The simulation failed to run. 'l|_$3  
Error:  Can not find result 'E' in the result provider 'field' {n]sRz  
代码如下：  qR qy  
radius = 1e-6*[0.25,0.75]; 4*x!B![]y  
for (i=1:length(radius)) { ?^~"x.<nr  
    setnamed("::model","radius",radius(i)); YJ$ewK4E#.  
    run; CeTr%j  
    E = getresult("field","E"); H|UL5<:]D  
    x = E.x;  3Mx@  
    z = E.z; )\-";?sYky  
    Ex = E.Ex; sw|:Z(`  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); 7X(]r1-+\
