MATLAB: How to add both a comma AND a carriage return to a file during export

carriage return

I would like to export a file of a vector like: xlswrite(filename,M) or csvwrite(filename,M)

Where M is a vector.

I would like the text file to look like:

1000,
2000,
3000,
...

etc.

Basically I would like to make the file with both a comma then a carriage return. I tried dlmwrite but you can only do one delimiter.

Any help would be appreciated.

You could use fprintf:

fid = fopen(fnm,'wt');
fprintf(fid,'%d,\n',M);
fclose(fid);

Remember to specify the format string to suit the desired number format.

Had to add

 input = textscan(fileID,formatSpec,'delimiter','\n','whitespace','');

MATLAB: Comma Separated Imported Data

S = fileread(FileName);
S(S == '"') = [];
fmt = '%f%f%f%f%f%f';
data = cell2mat( textscan(S, fmt, 'HeaderLines', 1, 'Delimiter', ',', 'CollectOutput', true) );

Now data is a numeric array with 6 columns.

Potentially you might want to use

dd = data(:,1:4);
dd(:,5:6) = 0;  %add minutes and seconds column
dt = datetime(dd);

Now dt would express the dates and times as datetime objects. That can be useful in analysis, such as

Wind_Direction = data(:,5);
Windspeed = data(:,6);
T = timetable(Wind_Direction, Windspeed, 'Rowtimes', dt);

and then you can do things like

retime(T, 'daily')

which would give you the daily average wind direction and windspeed.

(However, this in itself would not know about wrapping directions at 360 so the average wind direction could be wrong, such as near 2016,01,24,00)
