N<9 c/V  
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： /@F'f@;  
Warning: in run: there was no simulation data. The simulation failed to run. z_!IA ] v  
Error:  Can not find result 'E' in the result provider 'field' v-tI`Qpb  
代码如下： SO=gG 2E  
radius = 1e-6*[0.25,0.75]; `9co7[Z  
for (i=1:length(radius)) { V 9Qt;]mQ  
    setnamed("::model","radius",radius(i)); z'U.}27&o  
    run; {^z73Gxt,  
    E = getresult("field","E"); \ZZ6r^99  
    x = E.x; sfyLG3$/  
    z = E.z; ]>1Mq,!  
    Ex = E.Ex; mol,
iM*l  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); Nv
