Adding specific section of one text file to another

I have two text files, one with 523 lines and another with 516 lines. Line 14 of text file 1 matches line 5 of text file 2. I would like to merge everything from lines 1-13 in text file 1 to before line 5 of text file 2. However, I do not want to do it using the visdiff function. Any suggestions? Unfortunately I am unable to share the code or contents of the text files.

Hi Abraham Aguilar,

Like I don't have your text (or an example of that one with random words) I'm going to suposse that you have a string with differents line breaks. A line break is usually a

char(10) or newline

So you can search for these char.

linebreaks1 = strfind(str1,char(10));
linebreaks2 = strfind(str2,char(10));
Newtext = [str2(1:linebreaks1(4)),str1(1:linebreaks1(13)-1,str2(linebreaks2(4):end)]; %I have suposse that you want the 4 first lines of str2 before the str1 lines.
