title: R like str() function in matlab/GNU Octave
body: <p>I'd like to be able to view the structure of objects in Matlab/GNU Octave the same way as I do in R (using the <a href="http://stat.ethz.ch/R-manual/R-devel/library/utils/html/str.html" rel="nofollow"><code>str()</code></a> function). Is there a function that does this? An example task would be returning nr rows and cols in matrix, but also all the arguments for a given function.</p>
  
  <p>I'm aware that I could use both <a href="http://www.mathworks.co.uk/help/matlab/ref/size.html" rel="nofollow"><code>size()</code></a> and <a href="http://www.mathworks.co.uk/help/matlab/ref/help.html?searchHighlight=help" rel="nofollow"><code>help()</code></a> (but not for <a href="http://sunsite.univie.ac.at/textbooks/octave/octave_12.html#SEC95" rel="nofollow">function files</a>) separately to get this information.</p>
