[求助]请问下面这段代码中setnamed命令中的几个分别代表什么意思啊？ [复制链接]

@3KVYv,q  
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： ,\!4A  
Warning: in run: there was no simulation data. The simulation failed to run. ]#R'hL%f  
Error:  Can not find result 'E' in the result provider 'field' a(Ka2;M4J  
代码如下： '<~rV  
radius = 1e-6*[0.25,0.75]; UgDai?b1  
for (i=1:length(radius)) { :khl}|  
    setnamed("::model","radius",radius(i)); @Tb T  
    run; 9\i;zpN\  
    E = getresult("field","E"); 6cz%>@  
    x = E.x; - {<`Z  
    z = E.z; Onb*nm  
    Ex = E.Ex; *

    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); _d6mf
