Reading from Multiple files

I have my code as listed below reading from 60 files. Is it possible to reduce this coding? Please help.

ex = actxserver('excel.application');
ex.visible = 1;
%---------------------------------------------------
exwb1 = ex.Workbooks.Open('C:\Advisory\1.xls');
exwb2 = ex.Workbooks.Open('C:\Advisory\2.xls');
:
:
exwb60 = ex.Workbooks.Open('C:\Advisory\60.xls');
%---------------------------------------------------
exSheet1=exwb1.Sheets.Item('Compile');
exSheet2=exwb2.Sheets.Item('Compile');
:
:
exSheet60=exwb60.Sheets.Item('Compile');
%---------------------------------------------------
for j=[2:16 21:27]                              
    L=xlsColStr(j); 
    i=7;
    val1 = exSheet1.Range([L,num2str(i)]).get('Value');
    val2 = exSheet2.Range([L,num2str(i)]).get('Value');
    :
    :
    val59 = exSheet59.Range([L,num2str(i)]).get('Value');
    sum=val1+val2+.......+val59;
    exSheet60.Range([L,num2str(i)]).set('Value',sum);  
end
