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： edC4BHE  
Warning: in run: there was no simulation data. The simulation failed to run. ]s1 YaNq  
Error:  Can not find result 'E' in the result provider 'field' m7|RD]q&  
代码如下： 8<#U9]  
radius = 1e-6*[0.25,0.75]; /2uQCw&x-  
for (i=1:length(radius)) { ;[0&G6g  
    setnamed("::model","radius",radius(i)); tiaR4PB  
    run; nKh&-E  
    E = getresult("field","E"); NucM+r1P  
    x = E.x; P`SnavQBt  
    z = E.z;  u\e\'\  
    Ex = E.Ex; :14i?4Fd  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); -=}3j&,\R
