This is not a good idea, you can save all your data in one cell array
filename={'amit.txt','ankit.txt','anmol.txt'}
for k=1:numel(filename)
data{k}=dlmread(filename{k})
end
% to get file names automatically
folder='E:/Matlab'; % for example
f=dir([folder '/*.txt'])
for k=1:numel(f)
data{k}=dlmread(f(k).name)
end
