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： .
U 39nd  
Warning: in run: there was no simulation data. The simulation failed to run. &U&Zo@ot"x  
Error:  Can not find result 'E' in the result provider 'field' jn^fgH?  
代码如下： uJY.5w  
radius = 1e-6*[0.25,0.75]; dMJ!>l>2  
for (i=1:length(radius)) { -KiRj!v|  
    setnamed("::model","radius",radius(i)); kbhX?; <`  
    run; OF8WDo`  
    E = getresult("field","E"); <7^Kt7k  
    x = E.x; 6 Uw;C84!  
    z = E.z; Aq"PG}Ic  
    Ex = E.Ex; !lhFKb;  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); ra]:$XJ5=a
