在 MATLAB Online 中打开

"Classic" date numbers...

>> datestr(addtodate(datenum('10:12:49','HH:MM:SS'),526,'second'),'HH:MM:SS')
ans =
10:21:35
>>

There's a new date/time class w/ built in methods if have later version to do same thing.

Thank you very much. Can you please help me with one more problem: I have a matrix with "second". Want to add them with the datenum and want to see the output in a file.

All the above functions are fully vectorized per Matlab general rules; simply replace the constants above with the appropriate variable(s).

After that, writing the output to a file is covered in the "Getting Started" documentation under "Data Import and Export" under the Section "Data and File Management"
