title: How to add a string as data to a dataset?
body: <p>I use the following code to create a simple dataset and add the first two rows:</p>
  
  <pre><code>data = dataset([1; 2],[3; 4],'VarNames', {'A', 'B'})
  </code></pre>
  
  <p>After that, I would like to set the value 4 to 'test':</p>
  
  <pre><code> data(1,2) = 'test'
  </code></pre>
  
  <p>Since this throws the following exception:</p>
  
  <pre><code>Error using dataset/subsasgnParens (line 198)
  Right hand side must be a dataset array.
  Error in dataset/subsasgn (line 79)
      a = subsasgnParens(a,s,b,creating); 
  </code></pre>
  
  <p>I also tried:</p>
  
  <pre><code>data(1,2) = dataset('test');
  </code></pre>
  
  <p>But this is also not working. Therefore my question: How can I add a String to a dataset such as I have created, using the method I'm using (I have to specify the row and column)?</p>
