If you assume, that there is an error and want others to solve it, it is useful to mention, what you observe. I cannot guess, what you call "error" here. Do you get an error message? If so, post a copy of the complete message.

Add the new information by editing the question, not by appending a comment.

I faced the same problem, but here is one solution. This line

file = fopen('Data/source_data.txt');

will open the file 'source_data.txt', which is present in a inner folder named 'Data'.

If you are simulating online, then you have to upload that file also, and also you have to change the corresponding location.

I have upoladed it with the codes and didn't made anyinnder folder, so I have changed the code to this:

file = fopen('source_data.txt');

Remember you have to chenge another line.

f = fopen('Data/received.txt','w+');

to

f = fopen('received.txt','w+');

Hi Doaa,

As per my understanding, you are trying to perform read operation on a text file.

Based on my assumption, the error might be present in the “fopen” command. For it to work, the text file “source_data.txt” must be present in the MATLAB path or the complete location of the file needs to be passed as an argument to the “fopen” command.

You can access the related documentation of “fopen” command and “adding folders to MATLAB path” here

Open file, or obtain information about open files - MATLAB fopen - MathWorks India

Add folders to search path - MATLAB addpath - MathWorks India

Hope this answer helps you.

Thanks,

Bhanu Prakash.
