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： ^uy2qO4Yw  
Warning: in run: there was no simulation data. The simulation failed to run. mN9Uyz5G  
Error:  Can not find result 'E' in the result provider 'field' :cmQ w  
代码如下： d/Z258  
radius = 1e-6*[0.25,0.75]; 2[*r9%W  
for (i=1:length(radius)) { \3ZQ:E}5  
    setnamed("::model","radius",radius(i)); 9_6.%qj&  
    run; .kGlUb?^Q  
    E = getresult("field","E"); x*9CK8o=  
    x = E.x; Jhyb{i8RR  
    z = E.z; 0> 6;,pd"  
    Ex = E.Ex; x 7;Zwd  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); A!K/92[#@
