請問大家下面這段代碼中setnamed命令中的幾個分別代表什么意思��？腳本運行的時候發(fā)現(xiàn)半徑為0.25μm時可以正常運行，但為0.75μm的時候出現(xiàn)一個錯誤： _K!)0p  
Warning: in run: there was no simulation data. The simulation failed to run. roi,?B_8  
Error:  Can not find result 'E' in the result provider 'field' z X+i2,  
代碼如下： 4B[uF/[  
radius = 1e-6*[0.25,0.75]; gL@]p  
for (i=1:length(radius)) { 4qd(a)NdY  
    setnamed("::model","radius",radius(i)); LF
{8hC[  
    run; !4z vkJO  
    E = getresult("field","E"); 8wkt9
:  
    x = E.x; zlkW-rRkR  
    z = E.z; R9K~b^`  
    Ex = E.Ex; }dU!PZ9N)  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); '!MKZKer
