Insert value for the last day of the year

Hi,

enclosed you will find a 1044x1 datetime vector (weekly data).

I would like to create a logical vector containing 1 for the last data point of each year.

Do you have any suggestions?

Thank you for your help.

May be a neat way with the builtin datetime lookup functions, but first thing that comes to mind is

isyrlast=false(size(dates));
isyrlast(arrayfun(@(y) find(year(dates)==y,1,'last'),unique(year(dates))))=true;
