How to Select a distinct subset of a CellArray

Asked by Léon on 17 Jun 2013

Hello,

please consider the following problem:

x = {1,1;1,2;1,3;2,1;2,2}
[C,IA,IC] = unique(x(:,1))
C(1) % ==> is 1, now I want to get all rows of x where we have a 1 in the first column.

Would be super glad to get a tip how to achieve that!

x = [1,1;1,2;1,3;2,1;2,2];
out = x(x(:,1) == 1,:);
