我利用comsol做好一個案例后，需要大量改變一個參數值，于是我將mph文件保存為m文件，加入了一個for循環，利用comsol with matlab運行，但是顯示錯誤，哪位大神曉得怎樣在comsol生成的m文件里加入for循環？下面是程序：

% COMSOL Multiphysics Model M-file

% Generated by COMSOL 3.5a (COMSOL 3.5.0.603, $Date: 2008/12/03 17:02:19 $)

% Some geometry objects are stored in a separate file.

% The name of this file is given by the variable 'flbinaryfile'.

flclear fem

clear vrsn

vrsn.name = 'COMSOL 3.5';

vrsn.ext = 'a';

vrsn.major = 0;

vrsn.build = 603;

vrsn.rcs = '$Name: $';

vrsn.date = '$Date: 2008/12/03 17:02:19 $';

fem.version = vrsn;
