Question

I want to access several sequenced folders

Example :

[ndata, text, alldata] = xlsread(' D: \ folder \ 1 \ file ' ) ;
[ndata, text, alldata] = xlsread(' D: \ folder \ 2 \ file ' ) ;
[ndata, text, alldata] = xlsread(' D: \ folder \ 3 \ file ' ) ;
[ndata, text, alldata] = xlsread(' D: \ folder \ 4 \ file ' ) ;

Could I replace 1,2,3and 4 by variable i .. How could the directory be written here ?!

Please need any recommendation !

Answer 1

Yes, you can. Use the sprintf() command.

i=1;
[ndata, text, alldata] = xlsread(sprintf('D:\\folder\\%i\\file',i))

To make sure this is working right, change the sprintf to a fprintf, and make sure the file exists.

>> i=1;
>> fprintf('D:\\folder\\%i\\file',i)
D:\folder\1\file
>> ls D:\folder\1\file
