How to avoid the multiple use of 'unique' to filter inconsitent datasets?

Question

I have two corresponded (has a relation and has the same dimension) dataset:

1. Time
2. Salinity

Some data in Time dataset are duplicated.

I can remove the duplicate value by:

Time_new=unique(Time,'rows');

But it will not correspond to the Salinity dataset any more.

How can I adjust the corresponded Salinity Data in also?

Thanks

Answer 1

Use the additional output arguments of unique:

[Time_new,idx_un,~] = unique(Time,'rows');
Salinity_new = Salinity(idx_un, :);
