I have a 1443x1 double which is made up of time matlab serial numbers but when I try to use datetime to convert the serial numbers to the format HH:mm:ss.SSS I get the following error: "Input data must be one numeric matrix when converting from a different date/time representation." How do I convert the double to make this work? Thanks in advance!

Typically you would use the 'ConvertFrom' name-value pair.
t = datetime(X,'ConvertFrom',dateType)
Select the appropriate datatype here.

This is what I was using: t = datetime('serialtime','ConvertFrom','datenum','Format','HH:mm:ss.SSS'); with serialtime being the 1443x1 double

Ran in:
Don't pass in the char vector 'serialtime'. Pass in the variable serialtime.
x = 'abracadabra';
length('x') % the word 'x' is 1 character long
ans = 1
length(x) % the word stored in the variable named x is 11 characters long
ans = 11
