title: Import matlab with space and tab delimiter
body: <p>I need to import a txt file into Matlab which has this format</p>
  
  <pre><code>text text text           
  1           0 1 2 3
              4 5 6 7
  2           10 11 15 18
              15 1 18 3
  </code></pre>
  
  <p>The first column is separated with the second one by a tab delimiter, while the rest of the data are separated by a space.
  I tried to import it using this:</p>
  
  <pre><code>g = importdata('file.txt',delimiterIn,headerlinesIn);
  delimiterIn = ' ';
  headerlinesIn = 1;
  </code></pre>
  
  <p>but then the extracted table is like this:</p>
  
  <pre><code>text text text  
  1 0 1 2 3
  4 5 6 7 nan
  2 10 11 15 18
  15 1 18 3 nan
  </code></pre>
  
  <p>What I want is a table that maintains the format, with the first column of g.data on its own and then all the others.</p>
  
  <p>I want an output matrix like</p>
  
  <pre><code>1 0 1 2 3
    4 5 6 7
  2 10 11 15 18
    15 1 18 3
  </code></pre>
  
  <p>Then if I need to extract data represented by 2 in the first column, I can put it into another matrix with the values </p>
  
  <pre><code>10 11 15 18
  15 1 18 3
  </code></pre>
  
  <p>each number inside a cell of a matrix</p>
  
  <p>How can I do it?</p>
