how remove duplicate rows ?

I dont knew if we can have a script for that if we have

A=[ 1,2,3;
   42,0,1;
   14,2,4;
    2,3,5;
    1,0,0]

B=[42,0,1;
    1,0,0]

i want C

C=[ 1,2,3;
   14,2,4;
    2,3,5]

thanks

Note that the difference between my answer and Andrei's is how to handle the case where there are rows in B that are not in A. My solution will include those rows in C, and Andrei's will not.

Azzi's is different still, in that it handles replicated rows from A differently. My and Andrei's solution will keep only the unique rows, while Azzi's will keep duplicate rows from A.

Answer 1

[the cyclist]

C = setxor(A,B,'rows','stable')

Answer 2

[Andrei Bobrov]

C = setdiff(A,B,'rows','stable')

Answer 3

[Azzi Abdelmalek]

C=A(~ismember(A,B,'rows'),:);
