Q+wO\TtE  
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： =tY%`e  
Warning: in run: there was no simulation data. The simulation failed to run. xf8[&

代码如下： n%G[Y^^,  
radius = 1e-6*[0.25,0.75]; 'h7x@[|  
for (i=1:length(radius)) { Yk)fBPHr  
    setnamed("::model","radius",radius(i)); MxUbx+_N
