title: matlab: remove duplicate values
body: <p>I'm fairly new to programming in general and MATLAB and I'm having some problems with removing values from matrix.</p>
  
  <p>I have matrix tmp2 with values:</p>
  
  <pre><code>tmp2 = [...      ...
          0.6000   20.4000
          0.7000   20.4000
          0.8000   20.4000
          0.9000   20.4000
          1.0000   20.4000
          1.0000   19.1000
          1.1000   19.1000
          1.2000   19.1000
          1.3000   19.1000
          1.4000   19.1000
          ...      ...];
  </code></pre>
  
  <p>How to remove the part where on the left column there is 1.0 but the values on the right one are different? I want to save the row with 19.1. I searched for solutions but found some that delete both rows using histc function and that's not what i need.</p>
  
  <p>Thanks</p>
