<em>rank</em>(&lt;matrix\_expression&gt;)

<em>rank</em>calculates the rank of its matrix argument.

</TT></PRE><P>The argument to <em>rank</em> can also be a 
<A HREF=r37_0053.html>list</A> of lists, interpreted 
either as a row matrix or a set of equations. If that form of input is 
chosen, the vectors in the result will be represented by lists as well. 
This additional input syntax facilitates the use of <em>rank</em> in 
applications different from classical linear algebra.
