Find indices of matching date times

Hi,

I have 2 tables containing a column datetime. How can I find the first DateTime of table A in table B?

So if Table B contains 20 DateTimes. How can I find the index of the matching datetime from table A?

Have you tried ismember? It will probably be close to what you need.

You can refer to the following piece of code

s1 = {'2014-07-28' ; '2014-06-29' ; '2014-07-30'};
s2 = {'2014-08-01' ; '2014-07-30' ; '2014-07-9'};
t1 = datetime(s1,'InputFormat','yyyy-MM-dd')
t2 = datetime(s2,'Format','yyyy-MM-dd')
[logical_Index ,index] = ismember(t2,t1)
