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： N%,zME  
Warning: in run: there was no simulation data. The simulation failed to run. 48Jt5Jz_  
Error:  Can not find result 'E' in the result provider 'field' 
xk  
代码如下： Gshy$'_e  
radius = 1e-6*[0.25,0.75]; Bq;GO  
for (i=1:length(radius)) { +1a3^A\  
    setnamed("::model","radius",radius(i)); QH,Fw$1  
    run; 1:iB1TclP  
    E = getresult("field","E");  &1f3e  
    x = E.x; ?@z/#3b  
    z = E.z; !PA><F  
    Ex = E.Ex; 1 0zw}1x  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); jo?[M  
    switchtolayout; o[1#)&
