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： Lvk}%,S8t  
Warning: in run: there was no simulation data. The simulation failed to run.

代码如下： 6Q.S  
radius = 1e-6*[0.25,0.75]; *S$vSDJCW  
for (i=1:length(radius)) { IwYeKN6s  
    setnamed("::model","radius",radius(i)); \Mf>X\}  
    run;  Fr%#  
    E = getresult("field","E"); M`MxdwR  
    x = E.x; p/H.bG!z  
    z = E.z; /y$Omc^  
    Ex = E.Ex; %#6@PQ[R.  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); =c8}^3L~7
