Creating a file from different-sized files.

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
