I have a data set with timestamps:
'11/5/2019 12 a.m. EST'
'11/10/2019 1 p.m. EST'
How can I convert these timestamps into a vector of date numbers?
thanks for the help.

So you're converting from strings to datenum?
It might be necessary to remove the dots first using strrep but maybe not (my machine has been shut down for the night).

Assuming there is ".m. EST" attached to each "timestamp" at the end. You can follow the steps:
Step-1 Replace ".m. EST" to just "m" (Hint : regexprep)
Step-2 Convert the output into the date numbers (Hint: datenum)
You should get the output with date numbers in a array. (Not sure what do mean by "continuous"?)

Instead of the regexprep() you could also do
temp = strrep(S,'.','');
