Z = [1 2 5 7 8 3 0 4]
How can I obtain Z1 = [1 2 0 0 0 3 0 4] from Z using the Matlab logical operators?

I can use this to get the same answer Z1 = Z - [ 0 0 5 7 8 0 0 0] but I am not sure whether that is the right way or not? Any help?

index = Z<5;

Z1 = Z(index);

I guess Mario is looking for this:

Z(Z<5) = 0;

Best.

This gives >> index = Z<5

index =

     1     1     0     0     0     1     1     1

>> Z1 = Z(index) 

Z1 =

     1     2     3     0     4
but not the 1 2 0 0 0 3 0 4

It is not right and I am trying to manipulate to get it right.
 Z(Z<5) = 0

Z =   0     0     5     7     8     0     0     0

Hi Mario, one way

Z = [1 2 5 7 8 3 0 4];
Indices = find(Z<5);
Z1 = double(Z<5);
Z1(Indices)=Z(Indices);

Wayne

I am sorry. I got it the other way around. This should work:

Z(Z>4) = 0;

Best.

Here is an one-liner:

Z = [1 2 5 7 8 3 0 4] ; 

Z1 = Z .* (Z<5)

Well, that manipulation would be

z(~(z>5))   % Nota Bene: that Sadik posted his intended version... :)
