I am using some code to substitute values without the symbolic toolbox. The code follows.
  1. 1: B=A(A>2)
  2. 2: T=zeros(size(A)
  3. 3: mask=A>2
  4. 4: T(mask)=A(mask)
A represents an absolute value matrix. The lines of code remove any value less than 2. We want to modify code so that it instead removes anything greater than 2 AND anything less than -2.

Not sure what this has got to do with the symbolic toolbox. It's basic matlab.
Anything greater than 2 and anything less than 2 is anything not equal to 2, so:
T = A;
T(T~= 2) = 0;

I wanted to change the range -2<A<2 to 0 Not just 2.

Nevermind. I figured it out
T=A;
T(abs(T)<2)=0;
