%% Elements Equal to Specific Values % To find a specific integer value, use the |==| operator. For instance, % find the element equal to |13| in a 1-by-10 vector of odd integers. % Copyright 2015 The MathWorks, Inc. x = 1:2:20 %% % k = find(x==13) %% % To find a noninteger value, use a tolerance value based on your data. % Otherwise, the result is sometimes an empty matrix due to floating-point % roundoff error. y = 0:0.1:1 %% % k = find(y==0.3) %% % k = find(abs(y-0.3) < 0.001)
