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： s$j,9uRr  
Warning: in run: there was no simulation data. The simulation failed to run. &6VnySE?  
Error:  Can not find result 'E' in the result provider 'field' YT,{E,U;  
代码如下： 3Y$GsN4ln  
radius = 1e-6*[0.25,0.75]; =I_'
.b  
for (i=1:length(radius)) { S f# R0SA  
    setnamed("::model","radius",radius(i)); @r1_U,0e  
    run; R:qW;n%AF  
    E = getresult("field","E"); ~D>p0+-c  
    x = E.x; S_H+WfIHV'  
    z = E.z; 4Z0]oIX  
    Ex = E.Ex; h<QY5=SF  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); ~k5W@`"W
