Day Function not Working

Hello!

I have a cell array (question_display_time) filled with dates in the following format string = 'yyyy-mm-dd HH:MM:SS.FFF'.

When I try to run the day function Matlab returns the following: Undefined function 'day' for input arguments of type 'cell'.

When I try to run it on a sample string I get the following Undefined function 'day' for input arguments of type 'char'.

Am I doing something wrong? I thought this would be a simple function to grab the date with!

What I have tried: dayDate = cellfun(@day, question_display_time) day(string,'yyyy-mm-dd HH:MM:SS.FFF') day('2013-05-05 12:33:33.1234')

Any ideas? :)

day('2013-05-05 12:33:33','yyyy-mm-dd HH:MM:SS')

I still get the undefined function 'day' for input arguments of type char with this answer...

>> day('2013-05-05 12:33:33','yyyy-mm-dd HH:MM:SS') Undefined function 'day' for input arguments of type 'char'.

Type

which day

what do you get?

C:\Program Files\MATLAB\R2013a\toolbox\finance\calendar\day.m

it exists - I found an easier method to do this without using the day function

days = datestr(question_display_time,'dd')

Thank you for your help and quick responses
