title: How to use interpolation in MATLAB?
body: <p>Could anyone help how should I use the interp1-function on MATLAB on data such as the following:</p>
  
  <pre><code>   -99
       3
       1
       7
      10
      10
      22
      29
     -99
     -99
      25
      26
      60
     142
      78
     124
      74
      26
      13
      18
  </code></pre>
  
  <p>The -99 data values correspond to error-values and I would like to interpolate them...advices? =) Thank you!</p>
