Hello, I have a program,which takes start date and end date from user,I would like to use the variables as the filename when outputing to a .csv file. I have the following variables :

start_date =[2015, 1, 1];

end_date = [2015, 1, 2];

I want my csv file to be saved in this manner:

output_filename = "start_date " -- "end_date"--"data".csv.

Note: start_date is 1x6 double and end_date is 1x3 double and outputfilename is storing file name to be saved.

Thanks alot in advance.

在 MATLAB Online 中打开

 output_filename = [datestr(datenum(start_date), 'yyyy-mm-dd') ' -- ' datestr(datenum(end_date), 'yyyy-mm-dd') '--data.csv']

If you're used to C, you might find it easier to use sprintf() to create the filename.
