I wanna check outlier in my coordinates. Is there any function I can use in Matlab?

%for example I have coordinates in different systems.
datum1=[100,150,200] %xyz
datum2=[140,180,220] %xyz
%these are the same points but different coordinate systems. I wanna check any outliers in these coordinates.

If you consider the vast size of the Universe, and the number of atoms that exist, then one must conclude that bulk matter such as we have here on Earth is an "outlier" in the otherwise virtually empty cosmos.
Thus the appropriate function to remove outliers is to remove all data points completely. None of them matter, on a universal scale. If you think that they might matter on a local scale, then you are going to need to specify the local rules by which you determine that a point is an outlier in your context.
