Text file has no space between elements - Filename

I am trying to save a matrix (8760 x 1) to a text file. This is my code:

dlmwrite('totalenergy.txt',totalenergy,'delimiter',';','precision',4)

However, the generated text file has no space between the elements. Therefore, I get something like this:

5.845.845.655.776.016.196.286.096.045.283.99 etc.

Any ideas? Also, how can I insert a string variable into the filename of the .txt file? e.g. totalenergy_'X'.txt where X is a variable.

That's where the lines split, and you're probably looking at it in notepad or something. Double-click on it in the Current Folder panel of MATLAB and you'll see it looks normal.

Thank you for your quick reply, yes I did look at it in notepad. It does look normal anywhere else. I would appreciate your thoughts on my filename question.

Thank you in advance.

Use sprintf() and fullfile():

folder = 'C:\wherever';
baseFileName = sprintf('totalenergy_%d.txt', X) % where X is an integer.
baseFileName = sprintf('totalenergy_%.4f.txt', X) % where X is a double
baseFileName = sprintf('totalenergy_%s.txt', X) % where X is a string
fullFileName = fullfile(folder, baseFileName);
