Numeric array to serial datetime

I have a date and time in two columns, where date is datetime and time is a string. I want to convert these to serial datetime and further combine them, after importing I changed the table to arrays:

DA = table2array(Feed(1,1))

TA = table2array(Feed(1,2))

then the time from string to number:

t = str2num(TA)

then the date to serial datetime:

sdt = datenum(DA)

How can I convert the time (number array) into serial datetime? (In excel its typed as ex. 14.45 (only hour + minutes)

(I know how to combine them)

Perhaps something like this —

Feed{:,1} = datetime('29-Sep-2022');
Feed{:,2} = '14.45';
DT = Feed{:,1} + timeofday(datetime(Feed{:,2},'InputFormat','HH.mm'))

DT = datetime
   29-Sep-2022 14:45:00
