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： 
E?jb?  
Warning: in run: there was no simulation data. The simulation failed to run. JmuoYlf|  
Error:  Can not find result 'E' in the result provider 'field' ^Yo2R  
代码如下： )o;n2T#O  
radius = 1e-6*[0.25,0.75]; &-KQ m20n  
for (i=1:length(radius)) { K,!f7KKo  
    setnamed("::model","radius",radius(i)); =kw6<!R  
    run; i x_a  
    E = getresult("field","E"); zX8{
(  
    x = E.x; 5N907XVu  
    z = E.z; fK{Z{)D  
    Ex = E.Ex; /+m7

    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); 1#x@
