Select table data by Date

Hi,

I have a table, where the frist column is the date, and second column is a variable.

''2021-Jan-04'' -0.1581

''2021-Jan-04'' 0.0692

''2021-Jan-04'' 0

''2021-Jan-05'' -0.5150

''2021-Jan-05'' 0.2119

How can I select data in the second columb, by the date in the first colume?

Any help would be appreciated!

[C B]

dates = [datetime('today'); datetime('Yesterday') ;datetime('tomorrow')];
data = [-0.1 ; 0 ;0.1];
T = table(dates,data)

T = 3×2 table
       dates       data
    ___________    ____

    28-Oct-2021    -0.1
    27-Oct-2021       0
    29-Oct-2021     0.1

FindDate = '27-Oct-2021';
[val,index] = min(abs((datenum(T.dates)-datenum(FindDate))));
T.data(index)

ans = 0

FindDate = '29-Oct-2021';
[val,index] = min(abs((datenum(T.dates)-datenum(FindDate))));
T.data(index)

ans = 0.1000

FindDate = '28-Oct-2021';
[val,index] = min(abs((datenum(T.dates)-datenum(FindDate))));
T.data(index)

ans = -0.1000
