Hello there,
I have a matrix with a sequence of numbers, as it referes to a conjunction of points coordenates, most of times this values became monotonous in one of the lines, I want to discart every point that do not change em both lines 1 and 2 at the same time. Example:
[0 0 0 1 1 1 2 2 2 3 3 3,
0 1 2 2 3 4 5 6 7 8 9 10]
I just want to select
[0 1 2 3,
0 2 5 8]

Hello Felipe. Try this:
A = [0 0 0 1 1 1 2 2 2 3 3 3,
0 1 2 2 3 4 5 6 7 8 9 10];
[C, ia, ic] = unique(A(1,:));
C = vertcat(C,A(2,ia));
The function "unique" returns the unique values in a array.
