%FIND_TARGET extract the indices of the target and outlier objects
%
%   [It,Io] = FIND_TARGET(A)
%
% Return the indices of the objects from dataset A which are labeled
% 'target' and 'outlier' in the index vectors It and Io
% respectively. A warning is given when no target objects can be
% found.
%
%   [It,Io] = FIND_TARGET(LABA)
%
% It also works when no dataset but a label matrix given

function [I1,I2] = find_target(a)

% first find the logical vector of target objects:
I = istarget(a);

% extract the indices:
I1 = find(I);

% if requested, also find the outliers:
if (nargout>1)
	I2 = find(~I);
end
