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： &GB:|I'%7  
Warning: in run: there was no simulation data. The simulation failed to run. &8g?4v  
Error:  Can not find result 'E' in the result provider 'field' b"vv>Q~U  
代码如下： 4DL)rkO  
radius = 1e-6*[0.25,0.75]; '8{Ne!y  
for (i=1:length(radius)) { wv\w;'  
    setnamed("::model","radius",radius(i)); Zw ^kmSL"  
    run; TwVlg;  
    E = getresult("field","E"); z6w3"9Um  
    x = E.x; :uK?4  
    z = E.z; ihP|E,L=L  
    Ex = E.Ex; .`4{9?bR  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); q&W[j5E  
    switchtolayout; =1Oj*x@*4
