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：
*(@L+D0N  
Warning: in run: there was no simulation data. The simulation failed to run. 200L  
Error:  Can not find result 'E' in the result provider 'field' N
8Rm})  
代码如下： }<6oFUZ  
radius = 1e-6*[0.25,0.75]; ;,Of\Efc|  
for (i=1:length(radius)) { 2U=/<3;u  
    setnamed("::model","radius",radius(i)); % JgRcx  
    run; SJ1w1^#Pz  
    E = getresult("field","E"); .Z(S4wV  
    x = E.x; j CTQsV  
    z = E.z; ORV}j,Ym  
    Ex = E.Ex; I}6
DoLbV  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); 2rPcNh9
