I have ref value as
ref = [9.8 13 10.51 12.2 10.45 11.4]
and In values as
In = [10.7 11 11.5 11.9 12]
I want to do following two things :
In value closest matches with ref value and then afterIn value is lower or higher than ref value. If it is lower than saved in array1 and if it is higher than saved in array2See the following code snippet as one of many solutions:
% it would be a much better style
% to initialize the result vectors here properly!
a1 = [];
a2 = [];
for i=1:length(P_in)
[value, ind] = min(abs(P_in(i) - P_ref));
if P_in(i) <= P_ref(ind)
a1 = [a1 P_in(i)];
else
a2 = [a2 P_in(i)];
end;
end;
with the given vectors
P_ref = [9.8 13 10.51 12.2 10.45 11.4];
P_in = [10.5 11 11.5 11.9 12];
I get the following result:
array1 = [10.5000 11.0000 11.9000 12.0000]
array2 = [11.5000]
If you have a fixed deviation that is allowed for values to be 'close', the key part of your question can be solved with the ismemberf File Exchange Submission.
Basic syntax:
[tf, loc]=ismemberf(0.3, 0:0.1:1)
Can be exended by defining the allowed tolerance:
[tf, loc]=ismemberf(0.3, 0:0.1:1, 'tol', 1.5)
