I have an array of time series in the format dd-mm-yyyy hh:mm:ss, I want to convert it to datenum:
'29-May-1930 00:00:00'
'29-May-1930 01:00:00'
'29-May-1930 02:00:00'
'29-May-1930 03:00:00'
'29-May-1930 04:00:00'
'29-May-1930 05:00:00'
'29-May-1930 06:00:00'
'29-May-1930 07:00:00'
'29-May-1930 08:00:00'
'29-May-1930 09:00:00'
'29-May-1930 10:00:00'
How to do so?

What is wrong with the obvious
res = datenum( yourData );
?

Earlier, I put 'Inputformat','yyyy-mm-dd' and was getting error messages.

@Poulomi Ganguli: Did you notice that yyyy-mm-dd is arranged in a totally different order to your dates? And is missing the hour, minute, and second units? Instead of guessing what format string to use and getting it wrong, you could simply read the documentation:
https://www.mathworks.com/help/matlab/ref/datenum.html#inputarg_formatIn
and then try:
dd-mmm-yyyy HH:MM:SS
For example:
>> datenum('29-May-1930 00:00:00','dd-mmm-yyyy HH:MM:SS')
ans = 705067
