Combining vectors of day, month and year into a single date vector

Hi I have a set of data as an ASC file set up with 4 columns one has my data, the other three are the day (1-31), month (1-12) and year (1700-2000). How can I combine the day month and year into a single vector so that I can plot my data against the date in MATLAB?

So far I have imported each separate column into a vector but I am struggling to work out how to convert this into a vector of dates that I can actually use, any ideas?

[Lucas García]

dates = datenum([year,month,day]);

Then you can plot your data vs. dates.

Finally, use datetick to change the format of your dates' axis.

For example:

datetick('x','mmmyy')
