Remove values from column that are close in value to each other

I have a column of values:

43

90

91

128

191

192

I would like to remove the values that are close to each other in value, but keep the highest value.

I would want the column to look like this:

43

91

128

192

Is this possible or should I rethink my way of doing this?

One possibility:

x=[43
90
91
128
191
192];

[~,~,G]=uniquetol(x,10,'DataScale',1);

splitapply(@max,x,G)

ans = 4×1

43 91 128 192

x=sort(x);%make sure x is sorted
x(diff(x)<2)=[];
