MATLAB: How to create binary vector that can be applyied conditional case

Question

Hi guys,

I have input vector A (6×1), [ 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'(6×1) like this: [ 1, 1, 1, 0, 0, 0 ] and then calculate by each element.

In that way I can get the answer, C'(6×1) = [ 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

Answer 1

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
