How datetime and integer or float value can co-habitate in an array?

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)

Works perfect! I even included headers! thanks

[Azzi Abdelmalek]

Use cell array

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

or

   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

[yashvin]

@ Azzi Abdelmalek See this example, where array is a datetime array

array=[05-Feb-2015 18:14:23   05-Feb-2015 18:14:27   05-Feb-2015 18:14:31]
d=5.5
e=array(1)

I was meaning

f=[d e]

I want the output to be like

f= 5.5 05-Feb-2015 18:14:23

[Azzi Abdelmalek]

Have you read my answer? you can't write e=05-Feb-2015 18:15:59, it's

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

Also, I said you can use cell arrays

array={'05-Feb-2015 18:14:23' '05-Feb-2015 18:14:27' '05-Feb-2015 18:14:31'}
d=5.5
e=array(1)
f={d e}

[yashvin]

My result is

f=  [5.5000]    {1x1 cell}

I want to datetime to be displayed.

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

[Azzi Abdelmalek]

If you want to display it

f{1}
f{2}

[Walter Roberson]

Azzi probably meant

e = array{1}

rather than

e = array(1)

before the

f = {d e}

[yashvin]

It still does not work. What i am expecting is

   05-Feb-2015 18:16:03     5
   05-Feb-2015 18:17:43     3
   05-Feb-2015 18:19:55     1

The datetime value is side by side to an integer value and it should all be displayed at one time. The datetime value i am extracting it from a timestamp values of arrays that is very large.

[Walter Roberson]

t = datetime('now','TimeZone','local','Format','d-MMM-y HH:mm:ss Z');

{t 3; t 5}

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]

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!
