how to subset vectors by date in matlab

If you have a vector of datetime values and you want to subset it to include only those values falls between a specific date range, you can use indexing in MATLAB. Here's an example:

main.m
% create a vector of datetime values
dates = datetime('now') - days(1):hours(1):datetime('now');

% define the date range
start_date = datetime('2022-10-01');
end_date = datetime('2022-10-31');

% subset the vector using indexing
subset_dates = dates(dates >= start_date & dates <= end_date);

10 lines

In this example, dates variable contains a vector of datetime values generated using datetime() function. Then, we define our date range using start_date and end_date variables. Finally, we create a subset of dates vector that only contains values between the start and end date by using the >= and <= operators in combination with the logical AND operator &.

After running this code, subset_dates variable will only contain datetime values falls between October 1, 2022 and October 31, 2022.
