I have an array where one column contains dates in the DD-MM-YYYY format. I am trying to use if statements to do certain things based on what the MM is of a given row. So far I have tried using strcmp( ) and contains( ), but I am not sure how to format it.
x = datetime(2021,12,13);
contains(x,'Dec');
strcmp(x,'Dec');
What is the correct way to format this so that matlab can identify the month component of the date in the array?

Ran in:
Note that the DATETIME object already includes the MONTH property, no other functions are required:
x = datetime(2021,12,13)
x = datetime
13-Dec-2021
x.Month==12
ans = logical
1

Use the month function, then do the comparison —
x = datetime(2021,12,13);
y = datetime(2021,11,13);
TFx = month(x) == 12
TFx = logical
1
TFy = month(y) == 12
TFy = logical
0
.
