Month function doesn't work with double anymore

Hello,

I have just updated to 2019a. My scripts have worked previously 2018 version and now they do not. I am recieving an error message,

"Undefined function 'month' for input arguments of type 'double'." I have not made any changes to my scripts between matlab software version change.

Any idea what is happening?

Thanks,

Eric

From the documentation:

‘m = month(t) returns the month numbers of the datetime values in t. The m output contains integer values from 1 to 12.’

It appears only to work with datetime variables.

Star,

I worked around by calling the datevec associated with the double array. Works perfectly now.

Thanks for the quick response!

As always, my pleasure!

I was going to suggest using datevec if you’re working with datenum format variables.
