I have multiple .txt files. From these files have the same three letters in their name. I want to create a new file that will contain the data of all the files that have the first three letters in their name (e.g. "ABC****P.txt, ABC****T.txt, BCA****P.txt, BCA****T.txt". I want to megre in one file the first two .txt and one file the last two .txt files)
could you help me please?

This should get you started (untested, but gives an outline of how you could do this):
D = 'path to the folder where the files are saved';
S = dir(fullfile(D,'*.txt'));
C = {S.name};
T = regexp(C,'^.{3}','once','match');
U = unique(upper(T));
for k1 = 1:numel(U)
X = find(strncmpi(C,U{k1},3));
N = numel(X);
A = cell(1,N);
for k2 = 1:N
F = fullfile(D,C{X(k2)});
A{k2} = ...whatever file importing that suits your file format.
end
M = vertcat(A{:});
F = sprintf('%s merged.txt',U{k1});
... save matrix M with filename F using whatever file exporting that suits your data
end

Have you read the documentation for every function you didn't understand in the answer?
Let me give you a short-cut: read the documentation for sprintf.
