title: Solving an inequality with the "<>" in MATLAB
body: <p>How to solve an inequality in MATLAB with the <code>&lt;&gt;</code> operator, 
  I tried to run the following example (the solution is <code>x=y</code> or <code>y</code>):</p>
  
  <pre><code>syms x y;
  eqn1 = x^2==y^2;
  eqn2 = 3*x&lt;&gt;3*y;
  eqn = [eqn1 eqn2];
  solve(eqn)
  </code></pre>
  
  <p>but I get an error. The help doesn't give <a href="https://www.mathworks.com/help/symbolic/solve.html#bue6nzl-10" rel="nofollow noreferrer">an answer</a>.
  If there's not a built-in solution, how can I specify the values to except for the <code>solve</code> function</p>
