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： H^.IY_I`U*  
Warning: in run: there was no simulation data. The simulation failed to run.
tZ`
z  
Error:  Can not find result 'E' in the result provider 'field' d}JP!xf%  
代码如下： yU8{i&w4  
radius = 1e-6*[0.25,0.75]; ]8T |f  
for (i=1:length(radius)) { Zs}5Smjl;%  
    setnamed("::model","radius",radius(i)); +hE(Ra#  
    run;
Eh =~T9  
    E = getresult("field","E"); Y`o+XimX  
    x = E.x; RRGWC$>?  
    z = E.z; ,
Z{d.[$  
    Ex = E.Ex; ~=KJzOS,S  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); %I-+Ead0i
