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： .Ee8s]h5W  
Warning: in run: there was no simulation data. The simulation failed to run. Po2YDj`  
Error:  Can not find result 'E' in the result provider 'field' *"#>Ov>  
代码如下： ISl'g'o  
radius = 1e-6*[0.25,0.75]; a7+BAma<  
for (i=1:length(radius)) {
6} 9A0  
    setnamed("::model","radius",radius(i)); HJ2]xe09  
    run; |h#mv~cF  
    E = getresult("field","E"); y]/{W}D  
    x = E.x; { "/@,!9rJ  
    z = E.z; DI*xf Kt  
    Ex = E.Ex; 0q/g:"|j  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); ?Z;knX\?J
