Hi,
How do I add lines in a text file in a specific location using MATLAB ? For example, assume this is the text file I am reading into MATLAB
Sample line 1
Sample line 2
Sample line 3
Sample line 4
Interested location
Sample line 5
I want to add 'New sample line' right above the 'Interested location' so that my resulting file will be,
Sample line 1
Sample line 2
Sample line 3
Sample line 4
New sample line
Interested location
Sample line 5
____________
Is this possible?
Thanks,
Varshini

Read it in, add the line, write it out again. What aspect of it is causing a problem?

I have posted longer explanations in the past, but they come to the above: best is to copy from input to output until you have a change to make, then write the change to output, then copy the rest of the input to output

Hi
You may check my Matlab to LaTeX Library
I updated it with the following funciton: fc_lib_latex_string_add_lines.
This function I created to insert a given string into another given string at the lines given by a numeric vector. When I saw your question I remebered my solution and updated the package.
It is not dependent of LaTeX to work. It is only in the same library because it helps me to wirte LaTeX reports directly from Matlab.
Unfortunately, you have to give the numbers of line you want to insert your strings. Maybe in the future the selection of lines can be done with a different rule.
