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： nrR2U`  
Warning: in run: there was no simulation data. The simulation failed to run. 2({|LQqk  
Error:  Can not find result 'E' in the result provider 'field' m'-QVZ{(M%  
代码如下： *M.,Yoj  
radius = 1e-6*[0.25,0.75]; Za]~[F  
for (i=1:length(radius)) { Z23T

    setnamed("::model","radius",radius(i)); V\AY=u  
    run; (+SL1O P  
    E = getresult("field","E"); kN6jX

    Ex = E.Ex; v'm-A d+4t  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); h; 6G~D
