<div><h1>matrices</h1>
<div><h2>An overview</h2>
In Macaulay2, each matrix is defined over a ring, (see <a href="_rings.html" title="">rings</a>). Matrices are perhaps the most common data type in Macaulay2.<p/>
For additional common operations and a comprehensive list of all routines in Macaulay2 which return or use matrices, see <a href="___Matrix.html" title="the class of all matrices">Matrix</a>.</div>
