%FINDNLAB Determine indices of specified classes (numeric)%%    J = FINDNLAB(A,NLAB)%% INPUT%     A        Dataset%     NLAB     vector with numerical indices of reqested classes%% OUTPUT%     J        vector of sample indices%% DESCRIPTION% J is a column vector of indices to the objects in A that have one of the% numeric labels stored in NLAB. Note that NLAB should contain indices to% the labellist of A, which may be retrieved by LABLIST = GETLABLIST(A).% This command thereby retrieves the indices to all objects a specific class% or set of classes.
