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： wrSw>sE"  
Warning: in run: there was no simulation data. The simulation failed to run. U(4>e!  
Error:  Can not find result 'E' in the result provider 'field' kc Q~}uFB  
代码如下： ^_0zO$z,  
radius = 1e-6*[0.25,0.75]; VJ8cls<  
for (i=1:length(radius)) { 3MPmLV#f  
    setnamed("::model","radius",radius(i)); 0hVw=KDO9:  
    run; F=?0:2P0bD  
    E = getresult("field","E"); e*{'A  
    x = E.x; P|`pJYe  
    z = E.z; yr8 b?m.x  
    Ex = E.Ex; 4! ]28[2B6  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); "#Qqwsw7  
    switchtolayout; X,D
