Hi to all
I have these files consisting of two variabilities, so I want to create one formatted text file
start from the Line_2.mat, it will be the four rows of a now_file, then from the second file TT.txt, I want to add the table to now_file.

Which variable in Line_2.mat are you talking about? And have you made an attempt at solving this? If so, post your code.

@Nada,
Line_2.mat contains several variables. Let's assume you are interested in the one called Data. To append the data in TT.txt, do the following:
load('Line_2.mat'); % loads all the data in Line_2.mat
A=importdata('TT.txt'); % structure A contains the headers and the data
DataAll=[Data;A.data]; % combine
fprintf('Size of Data=%d x %d.',size(Data))
Size of Data=20709 x 9.
fprintf('Size of A.data=%d x %d.',size(A.data))
Size of A.data=8536 x 9.
fprintf('Size of DataAll=%d x %d.',size(DataAll))
Size of DataAll=29245 x 9.
save('DataAll.txt','DataAll','-ascii') %save combined data to text file
Try it. Good luck.

Did you want something like this? Note, I attached an import function called importTTfile.
load('Line_2.mat')
TT = importTTfile('TT.txt')
TT = 8536×9 table
