Create a matrix full of dates

Hi!

I need to create a matrix whit dates, starting in a specific date, for example '2013-04-01 22:00:59', and increasing in the interval of my choosing (like 1 sec, 1 min, ...).

I need to define the last one date also.

Could anyone help me?

Thank you in advance

Matrices can store only numbers. However, you can create cell-arrays, and struct-arrays in MATLAB. For example, see, http://www.mathworks.com/help/matlab/matlab_external/create-cell-arrays.html?searchHighlight=cell+array.

Now you can build a date string, using the function, datestr, http://www.mathworks.com/help/matlab/ref/datestr.html?searchHighlight=datestr and you should use the input as your increment time, obtained with the function now()

Yes sorry I meant that I need to create a cell-array with dates...

What I am doing is geting the first date into my array, and increment it with the interval i want. But I have problems to define this interval...I think it would be an easier solution for this.

If you just want to increment from a fixed point, then that's pretty straightforward.

 t0 = datenum('2013-04-01 22:00:59');
 dt = 1/(24*60*60); % 1 second

 t = datestr(t0 + (1:100)*dt);

Or do you not want the times to increment from the exact start date, but rather something like "increment by 1 hour on the hour" (so for your example, 23:00:00 would be the next, rather than 23:00:59)?

No thank you that is exactly what I was looking for. But one more question, how could I acces to a specific date into this vector? Because t(x) do not work...

[Leah]

t = cellstr(datestr(t0 + (1:100)*dt));

or reference t(x,:)

It works thank you!
