I was wondering if anyone could help with formatting a huge amount of data that I have?
The data that I will be formating is the date and time that a bunch of sensors were activated. The format of the raw data is yyyy-mm-dd hour:min:sec and I need to change it to dd-mm-yyyy hour:min:sec.

I have been trying to change the format using datenum, datestr, and datevec and have been successful in changing one date at a time but this is not time efficient and I can't figure out how to change the format for the entire data file. Thanks for your time I really appreciate any input.

Any reason not to toss the data into a char array, one date per line, and then
to do simple array indexing:

NewDates = Dates(:,[7:10 3:6 1:2 11:end]);
