datefind (Financial Toolbox)

Indices of date numbers in matrix.

Syntax

ind = datefind(sub, super, tol)
ind = datefind(sub, super)

Arguments

sub: Subset matrix of date numbers used to find matching date numbers in super. These date numbers must be a non-repeating subset of those in super.

super: Superset matrix of non-repeating date numbers whose elements are sought.

tol: Tolerance (+/-) for matching the date numbers in super. A positive integer. Default = 0.

Description

ind = datefind(sub, super, tol)

returns a vector of indices to the date numbers in super that are present in sub, plus or minus the tolerance tol. If no date numbers match, ind = [].

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

Example

super = datenum(1997, 7, 1:31);
sub = [datenum(1997, 7, 10); datenum(1997, 7, 20)];
ind = datefind(sub, super, 1)
ind =
     9
    10
    11
    19
    20
    21
