I am trying to save both a float or integer value together with a datetime value in an array. Anyway of making both these values cohabitate in an array?

   d= 5.5
   e = 05-Feb-2015 18:15:59
   f= [d e]

Of course this is an error. But I am trying to map integers values to a datetime value. How i can do this. Should i change the datetime to a string?

The datetime "e" is a string already. So you have actually:

e = '05-Feb-2015 18:15:59'

with the quotes.

Keep in mind that datetime is a newer object class, and members of that class print out without quotes.

Use a cell array, as Azzi said, or use a table object.

 x = 12345;
 t = datetime('today');
 A = table(x, t)

For a slightly larger table with some random data for today and the next 9 days:

 x = randi(100, 10, 1);
 t = datetime('today')+days((0:9).');
 t.Format = 'dd-MMM-yyyy'; % Adjust the formatting of the dates to display only day, month, and year
 A = table(x, t)

Use cell array

   d= 5.5
   e = '05-Feb-2015 18:15:59'
   f= {d e}

   d= 5.5
   e =datenum( '05-Feb-2015 18:15:59')
   f=[d e]

or use struct array

d= 5.5
e ='05-Feb-2015 18:15:59'
f.date=d
f.value=e

I do not understand this sentence:

 My second query is that my inital datetime array is very long
 (about 3000 in length)..how do i convert it automatically between commas?

yashvin 2015-6-29

Sorry for the confusion. What i meant is that i have a very long stream of datetime array. I wanted to display it in a column or table fashion whereby each datetime value corresponds to an integer!
