importing data to form a matrix

I have data in 2500 files with filenames like 1.txt, 2.txt etc. and each file has one column of data. I want one matrix that has all these columns.

I used A1 = importdata('1.txt') to read in one file

but how can I put filenames in loop to read all of them and get a matrix out of it?
