Integrating several text files

Hello

I have several text files which each of them contains thousands of numbers in 2 columns. I want to integrate them all into one file with the same formate, starting from the first row of the first file and ending with the last row of the last file.

Just read them in and concatenate.

b=[];
for n=1:numberoffiles
    fileName=sprintf('yourfile%d',n);%assuming file names are numbered
    a=readmatrix(fileName);
    b=[b;a];%concatenate
end

Thanks David,

What if the file names are not numbered ?

[Walter Roberson]

If they are not numbered, then which order do they need to be read in? For your purposes, is it okay if the data is put together in any "convenient" order, or does the name of the file influence the order it has to be placed in relative to the other files?

[Morteza Tohidi]

They are ordered by the file names change like this

XXX2020-2035

XXX2035-2055

XXX2055-2100

So it is not like simple numbers in row.

If you have a way to order them, you can read them in that order. Are you storing the file names in a struct or a cell?
