I'm working with nominative patent data from french applicants. So my file contains the name of the patent applicants. Each row is a patent, and each contains the name of one of the patent applicants. But there are duplicate. I would like to clean each row of the duplicate names (since each row is a patent and the names are in column).
Does anybody have an idea ?

Hello Heman,
Try using unique function which returns only the unique elements in the array.
newData = unique(yourData);
If you want the process to be non-case sensitive, for example if there are two elements 'Adam Smith' and 'adam smith', you can use lower function, and then unique function.
[~, idx] = (unique(lower(yourData)));
newData = yourData(idx)
I hope it helps.
