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： 5;WESk  
Warning: in run: there was no simulation data. The simulation failed to run. V{jQ=<)@e  
Error:  Can not find result 'E' in the result provider 'field' Dj?8

代码如下： onqifQ  
radius = 1e-6*[0.25,0.75]; b/[$bZD5o  
for (i=1:length(radius)) { s2Z'_rT  
    setnamed("::model","radius",radius(i)); olm0O (9  
    run; =Msr+P9Ai  
    E = getresult("field","E"); qQ&=Z`p!  
    x = E.x; zR@4Z>6   
    z = E.z; _HMQx_e0YM  
    Ex = E.Ex; [TX1\*W  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); u[:-^H  
    switchtolayout; p!oO}gE
