in help, I found this
Superset = datenum(1999, 7, 1:31);
Subset = [datenum(1999, 7, 10); datenum(1999, 7, 20)];
Indices = datefind(Subset, Superset, 5)
Indices =
5
6
7
8
9
10
11
12
13
14
15
15
16
17
18
19
20
21
22
23

25
here tolerance = (Optional) Tolerance (+/-) for matching the date numbers in Superset. but what to do if I want only previous dates. i.e.
5
6
7
8

Hi,
use
which datefind
to find the file datefind.m in the finance toolbox. Copy it to your folder and name it "mydatefind.m". Open in the editor and replace the line
i = find(d <= tol);
by
i = find(d <= tol & super<=sub(idx));
Hope this helps,
Titus
