yf_findeqindexes1.m

模糊C均值聚类的一个参考材料,做模糊聚类是用的一个程序

function Idx = Yf_FindEqIndexes1 (A, B, Epsilon)
%Idx = Yf_FindEqIndexes1 (A, B, Epsilon)
% 
%   returns find ( A == B)
%   Epsilon : optional (default: 1e-7)

if nargin < 3
    Epsilon = 1e-7;
end

    
% Note: find(A == B) do not works for all values!
Idx = find(abs(A - B) < Epsilon);
