datefind - Indices of date numbers in matrix

Syntax

Indices = datefind(Subset, Superset, Tolerance)

Arguments

Subset	Subset matrix of date numbers used to find matching date numbers in Superset. These date numbers must be a nonrepeating subset of those in Superset.
Superset	Superset matrix of nonrepeating date numbers whose elements are sought.
Tolerance	(Optional) Tolerance (+/-) for matching the date numbers in Superset. A positive integer. Default = 0.

Description

Indices = datefind(Subset, Superset, Tolerance) returns a vector of indices to the date numbers in Superset that are present in Subset, plus or minus the Tolerance. If no date numbers match, Indices = [].

Although this function was designed for use with sequential date numbers, you can use it with any nonrepeating integers.

Examples

Superset = datenum(1999, 7, 1:31);

Subset = [datenum(1999, 7, 10); datenum(1999, 7, 20)];

Indices = datefind(Subset, Superset, 1)

Indices =

          9
         10
         11
         19
         20
         21
