how to show miliseconds in a date string?

Hi everyone I am trying to generate an array of date strings in Matlab, but I need to see the miliseconds in the string. I havent found the correct format to do that, if anyone knows how to do that, please tell me.

Thanks

Include 'FFF' in the date specifier for datestr()

+1: DATESTR has an excellent error checking and accepts a variety of input formats. If the date conversion is not a bottleneck of the program, this is an efficient method.

MATLAB's date functions are very powerful, but this reduces their speed. If the dates need no verifications, because they have the correct format already, a direct approach is much faster. E.g. DATEVEC to dd-mmm-yyyy HH:MM:SS.FFF:

In = clock;
months = ['Jan'; 'Feb'; 'Mar'; 'Apr'; 'May'; 'Jun'; ...
          'Jul'; 'Aug'; 'Sep'; 'Oct'; 'Nov'; 'Dec'];
Out = sprintf('%.2d-%s-%.4d %.2d:%.2d:%06.3f', ...
              In(3), months(In(2), :), fix(In([1, 4, 5])), In(6));

If speed does not matter for this task, I recommend Walter's DATESTR+'FFF' method.
