Error in csvwrite for a specific filename

Question

0 个投票

Hi

I want to write a vector present in my workspace to a csv file. I'm adding a timestamp to the csv filename and for this I'm using

    fileName = sprintf('sampleData%s.csv', datestr(now));
    csvwrite(fileName,workspacevariable);

Wheneven I'm using the timestamp in the filename it's giving an error, without using a timestamp it works fine. Can anyone please help me in this ?

The file name contains characters that are not contained in the filesystem encoding.
Certain operations may not work as expected.

Thanks,

When I run that line I get:

fileName =
sampleData27-Jun-2016 13:54:24.csv

The problem (on Windows machines) are the colons (:). Those are not legal elements of any file name. Cbange the line to:

fileName = sprintf('sampleData_%s.csv', datestr(now, 'yyyymmdd_HHMMSS'))

creating:

fileName =
sampleData_20160627_135548.csv

and it should work.

Hi Star Strider,

Thanks a lot. Yeah it was the problem, I replaced all the ":" using strrep to "-" and it worked.
