title: Writing a mixed matrix of integers and strings to .csv in Matlab
body: <p>Perhaps this question has been answered before but I can't seem to find any good documentation on it.  So my problem is the following:</p>
  
  <p>Suppose I have two vectors of the same length in Matlab</p>
  
  <pre><code>x = [1;2;3];
  and
  y = ['A';'B';'C'];
  </code></pre>
  
  <p>Basically I would like to create the matrix <code>{x,y}</code> (ie 3 rows, 2 columns) and then write it to a .csv file.  So in the end I'd like to see a .csv file like</p>
  
  <pre><code>1,A
  2,B
  3,C
  </code></pre>
  
  <p>This is just a mocked-up example but really I have 75 columns with each being either a column of strings or numerics.  Any suggestions are greatly appreciated!</p>
