Hi all,
I have a 2D array int that has fixed avues of 1 on its second column but different values on its first column. How can I select the values from its first column to be within a range of .
int = [1.8702 1.0000 ; -0.8739 1.0000 ; 3.1069 1.0000 ; 0.9228 1.0000 ;-1.1946 1.0000 ; -0.1244 1.0000 ;...
0.2662 1.0000 ;0.3586 1.0000 ;0.2288 1.0000 ;0.0003 1.0000 ;-0.2503 1.0000];
Any help would be appreicted.

int(int(:,1) >= 0 & int(:,1) <= 1,1)

I know how:
int = [int(int(:,1) >= 0 & int(:,1) <= 1, 1) ...
int(int(:,1) >= 0 & int(:,1) <= 1, 2)];
Thank you.

That will work. A slightly simpler way is:
int = int(int(:,1) >= 0 & int(:,1) <= 1,:);
(I wasn't sure before if you wanted all the columns or just the first one.)
