Concatenate variable horizontally to make one variable in matlab

Question

Is it possible to concatenate multiple variable horizontally to make a single variable in Matlab?

For Example, I want to join:

year = 2001, month = 06, day = 15

to make one variable '20010615' which I could search in a matrix.

I hope I am clear.

Regards,

If you want a string output, use string formatting and sprintf

sprintf('%04d%02d%02d', year, month, day );

If you want a numeric output, simply multiply

day + 100 * month + 10000 * year

Update:

Thanks to @Joshua's comment: if you are indeed working with date/time information you should also look into datestr that allows more speciallized formatting for date and time information.

If you're interested in date strings specifically, datestr is the best tool for the job. E.g. it allows localization.
