Checking inequality condition for each component of a vector.

I think there is a bug and below is what I saw:

command: vec = [0;-5;6;1.99;-2.01;-2.001;0.5];

-0.1 < vec < 0.1

ans =

     0
     1
     0
     0
     1
     1
     0

command: -1.9 < vec < 2.1

ans =

     1
     1
     1
     1
     1
     1
     1

I need to apply piecewise univariate function for each component in my code. Can anyone suggest a way to get the correct result?

Unlike Python, you can't use multiple inequality expression in MATLAB. You'll have to do this :

-0.1 < vec & vec < 0.1

-1.9 < vec & vec < 2.1

To explain the result you saw, your command is equal to :

temp=-0.1 < vec;
temp < 0.1
