How can I change fileID name in a for loop?

Hi, I have this for loop

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

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');       

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

And when you read this section of the FAQ, read the rest also. It is very efficient to profit from the mistakes, which have been made repeatedly by others.
