HI,
I have an array:
angle =
Columns 1 through 5
174.8310 -4.9214 -5.0368 -5.0544 -4.2956
Columns 6 through 9
-2.9111 -5.0442 -5.7359 -5.0155
I would like to filter off the number that has less occurrence( Eg. 174.831 , -2.9111) while keeping those value that repeats.
Is there any matlab function that can do that?
Thanks

% Identify the elements that are too high or too low
isTooHi = (angle>-4.5);
isTooLo = (angle<-5.5);
% Remove them
angle(isTooHi|isTooLo) = [];

NONE of these numbers are repeated in your example! Unless you define what numbers are desirable, MATLAB cannot know that one number is better than another when all are distinct. MATLAB cannot read your mind.
My guess is you are looking for an outlier detection/removal scheme. If so, then you need to either define it in terms of the expected distribution of these numbers (i.e., a normal distribution) or do so using some non-parametric scheme.
