[Scilab-users] Remove duplicate rows and sustain original order of rows

[CHEZE David 227480]

Hi Iza,

Just consider this tip from the unique help page:

Extracted components, rows or columns can be resorted in their initial order by sorting k:
[N, k] = unique(M);      k = gsort(k,"g",i); N = N(k)
[N, k] = unique(M, "c"); k = gsort(k,"g",i); N = N(:, k)
[N, k] = unique(M, "r"); k = gsort(k,"g",i); N = N(k, :)

Hope it helps,

David

Objet : [Scilab-users] Remove duplicate rows and sustain original order of rows

Hi all,

I can't figure out how to remove duplicate rows from the matrix and go back to the original order of rows. Function "unique" with an option "r" 
sorts rows in lexicographic ascending order.

Thanks in advance for any help,
Iza
