title: read function from text file in matlab
body: <p>I'm going to read some function from a Unicode text file in matlab and calculate there answer with my own variables. first i use <code>fopen</code> to read the text file, then what should i do to convert each line of that text file to a function? for example the <code>func.txt</code> contains:</p>
  
  <blockquote>
  <pre><code>(x^2)-3y
  sin(x+z)+(y^6)
  </code></pre>
  </blockquote>
  
  <p>and i need to write an <code>m.file</code> which read <code>func.txt</code> and process that like this:  </p>
  
  <pre><code>function func1[x,y] =  (x^2)-3y
  function func2[x,y,z] =  sin(x+z)+(y^6)
  </code></pre>
