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： _8 C:Md`  
Warning: in run: there was no simulation data. The simulation failed to run. 9cqq"-$G`  
Error:  Can not find result 'E' in the result provider 'field' \8^c"%v,:  
代码如下： 0FAe5 BE7  
radius = 1e-6*[0.25,0.75]; -bP_jIZF;g  
for (i=1:length(radius)) { 
1 !8 b9  
    setnamed("::model","radius",radius(i)); q?##S'  
    run; E+"m@63  
    E = getresult("field","E"); eAl;:0=%L  
    x = E.x; zz m[sX}  
    z = E.z; Gnthz0\]{  
    Ex = E.Ex; huat,zLS  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); |& Pa`=sp
