I have a text file which i have created which has some data in it . I use '\n' to print each line on the next line using a for loop in the code .

I did this because i wanted to use 'textscan' later to create a cell array with this so that i can work on this file on Matlab.

BUt when i open the file in the directory , all the lines are printed one after the other , but in Matlab it shows the lines are well printed line after line .

I am attaching the text file i created and how it is showing on Matlab and when i open normally from the directory outisde Matlab.

Any help will be appreciated.I am attaching the code with it .Thank you.

在 MATLAB Online 中打开

You should fopen the file in TEXT mode:

fid = fopen(....'wt')
%                 ^ TEXT mode!

Or alternatively stop using retrograde Windows applications like Notepad.

"Why does the text file does not show me lines printed on next lines..."

Because you opened the file in BINARY mode which prints exactly the character that you requested (i.e. \n) but on Windows a new text line is indicated with two characters \r\n, which therefore your file does not contain and so your file is not shown on multiple lines. The simplest solution is to fopen the file in TEXT mode, which automatically makes this conversion for you.

This topic has been discussed thousands of times on this forum: search for "fopen newline".
