MATLAB: How to change fileID name in a for loop

Question

Hi, I have this for loop

for i=1:3
    if i==1
    fid = fopen('report_1.xls', 'wt');       
    end
    if i==2
    fid = fopen('report_2.xls', 'wt');        
    end
    if i==3
    fid = fopen('report_3.xls', 'wt');        
    end
end

In fact, I have much bigger than this loop. The problem is that I have to repeat fopen for each i. My question is can I avoid the if statements. So, the value of i can be written in fileID without adding it manually. For example,

for i=1:3
   fid = fopen('report_i.xls', 'wt');       
end

The above example will create a file named "report_i". However, I want to create 3 files named "report_1" , "report_2", and "report_3". How can I do that?

Thank you so much in advance
