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： O42An$}  
Warning: in run: there was no simulation data. The simulation failed to run. *yX_dgC>[  
Error:  Can not find result 'E' in the result provider 'field' y-Ol1R3:c#  
代码如下： sP&E{{<QTF  
radius = 1e-6*[0.25,0.75]; -51L!x}1c  
for (i=1:length(radius)) { IM@Qe|5  
    setnamed("::model","radius",radius(i)); HL!-4kN <$  
    run; \o3i9Q9C  
    E = getresult("field","E"); I7Eg$J&  
    x = E.x; }0!\%7-Q  
    z = E.z; @a3<fmJ  
    Ex = E.Ex; O;zW'*c+  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); dZYS5_wr  
    switchtolayout; }Jtaq[y\r
