I wish to remove all duplicate rows based off of the first column. That is, I want to just strip the excess away. I am struggling to understand how to implement "unique" here. Thanks in advance

If you want
- remove duplicates only based on values in the first column
- Do not want the returned values be sorted
then you need to do this
in=[[5;5;5;4;4;4;3;3;3;1],(1:10)'];
[~, index]=unique(in(:,1),'stable');
out=in(index,:)
