Hello everyone,
I'm trying to write a matrix to a CSV file but I keep getting an error saying the file cannot be opened. There are a lot of other posts bout this error but I still can't seem to get it working. Below is the code I've typed into the command window.
>> R = [1,2,3;4,5,6;7,8,9];
>> csvwrite('txt.csv', R)
Error using dlmwrite (line 130)
Could not open file txt.csv
Error in csvwrite (line 43)
dlmwrite(filename, m, ',', r, c);
>>
I can't understand why this error keeps occurring. Any help would be appreciated!

I cannot reproduce your error.
Error using dlmwrite (line 130)
^ Why did MATLAB tell you that you have error in dlmwrite when you're calling csvwrite? Did you copy everything and post them here? Try clearing your workspace and see if
>> R = [1,2,3;4,5,6;7,8,9];
>> csvwrite('txt.csv', R)
if it produce the same error?
And maybe you should check that you are in the correct MATLAB path. If you don't have permission to write in that folder, maybe that's the source of your problem.

I got the exact same error as Hikaru. Can not figure out why. I have the permission to write, it is also in the folder as other files from MATLAB is created. The path is included in MATLAB.

I got that same error for my data and for the code Hikaru posted. Turned out my current folder was root. Type pwd and make sure your current folder is the one you think it is.

Well, I had the same problem but I fixed it as soon as I changed the folder to the one I normally use for my Matlab files
