<div><h1>homology -- general homology functor</h1>
<div class="single"><h2>Description</h2>
<div>Most applications of this functor are dispatched through <tt>HH</tt>. If it is intended that <tt>i</tt> be of class <a href="___Z__Z.html" title="the class of all integers">ZZ</a>, <tt>M</tt> be of class <tt>A</tt>, and <tt>N</tt> be of class <tt>B</tt>, then the method for computing <tt>HH_i(M,N)</tt> can be installed with code of the following form.<pre> homology(ZZ, A, B) := opts -> (i,M,N) -> ...</pre>
