Hi All,

I am trying to create a new variables based on multidimensional array obtained, for the simplicity I just got the part of the code, I wanna do.

I just want to obtained only the dimension with different values :

For example: s(:,:,1), s(:,:,3), s(:,:,5).. the point is sometimes these values change so I would like to do it with a for a loop or whatever so whatever the dimension number .. I just want the new values with only the different numbers!!

Any help!!

clear all;
clc;
s(:,:,1)=[10;20;30];
s(:,:,2)=[10;20;30];
s(:,:,3)=[100;200;300];
s(:,:,4)=[10;20;30];
s(:,:,5)=[50;60;70];
s(:,:,6)=[10;20;30];
for i=1:2
    s_new(:,:,i)=s(:,:,i)
end

Not really sure what you are asking, but if you only want to pick off some indexes from an arbitrary dimension, simply supply them as a range or vector of indexes. E.g.,

s_new = s(:,:,1:2)

or

s_new = s(:,:,[1 2])
