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： "GO!^ZG]  
Warning: in run: there was no simulation data. The simulation failed to run. yV(#z2|  
Error:  Can not find result 'E' in the result provider 'field' }=[p>3Dd  
代码如下： s6,~JF^  
radius = 1e-6*[0.25,0.75]; *#T: _  
for (i=1:length(radius)) { dLiiJ6pl*  
    setnamed("::model","radius",radius(i)); -tj#BEC[H(  
    run; |nefg0`rk  
    E = getresult("field","E"); i1vz{Tc  
    x = E.x; WHdMP  
    z = E.z; EZ)b E9  
    Ex = E.Ex; ,|A^ <R`  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); "lh4Vg\7n
