Hi guys,
I have input vector A (6x1), [ 0.4, 0.8, 0.9, 1.0 1.1, 1.4 ] What I want to do is returning to zero if each value exceed one.
>> My idea is create a vector, B'(6x1) like this: [ 1, 1, 1, 0, 0, 0 ] and then calculate by each element.
In that way I can get the answer, C'(6x1) = [ 0.4, 0.8, 0.9, 0, 0, 0 ]
The questions is that is there any way to create binary vector like above?
Thanks in advances:D

A= [ 0.4, 0.8, 0.9, 1.0 1.1, 1.4 ]
B=A<1;
B=B.'
C=zeros(1,numel(A));
C(B)=A(B)
command window:
A =
0.4000 0.8000 0.9000 1.0000 1.1000 1.4000
B =
1×6 logical array
1 1 1 0 0 0
C =
0.4000 0.8000 0.9000 0 0 0
