Indices = datefind(Subset,Superset) returns
a vector of indices to the date numbers in Superset that
are present in Subset. If no date numbers match, Indices
= [].
Indices = datefind(___,Tolerance) returns
a vector of indices to the date numbers in Superset that
are present in Subset, plus the optional argument
for Tolerance. If no date numbers match, Indices
= [].
Subset of dates to find matching dates in Superset, specified as a matrix
using a datetime array, string array, or date character vectors.
Subset and Superset can be either be a datetime array,
string array, or date character vectors. These types do not have to match.
datefind determines the underlying date to match
dates of different data types.
Note
The elements of Subset must be contained in
Superset, without repetition.
datefind works with non-repeating sequences
of dates.
To support existing code, datefind also
accepts serial date numbers as inputs, but they are not recommended.
Data Types: char | string | datetime
Superset of dates, specified as a matrix of using a datetime array, string array, or date
character vectors, whose elements are sought.
Subset and Superset can be either a datetime array,
string array, or date character vectors. These types do not have to match.
datefind determines the underlying date to match
dates of different data types.
Note
The elements of Subset must be contained in
Superset, without repetition.
datefind works with non-repeating sequences
of dates.
Example: Superset = datetime(1997,7,1:31);
To support existing code, datefind also
accepts serial date numbers as inputs, but they are not recommended.
Data Types: char | string | datetime
Tolerance for matching dates (+/-) in Superset,
specified as a positive integer or duration object.
Indices of dates in Superset that are present in
Subset (plus or minus the tolerance if defined
using the optional argument Tolerance), returned as a
vector of indices.
Although datefind supports serial date numbers,
datetime values are recommended instead. The
datetime data type provides flexible date and time
formats, storage out to nanosecond precision, and properties to account for time
zones and daylight saving time.
To convert serial date numbers or text to datetime values, use the datetime function. For example:
t = datetime(738427.656845093,"ConvertFrom","datenum");
y = year(t)
y =
2021
There are no plans to remove support for serial date number inputs.
