<div class="single"><h2>Description</h2>
<div>The simplest use of this function is to define a matrix by giving a doubly nested list of ring elements. One may also explicitly provide the ring, or give a matrix as a doubly-nested list of matrices.<table class="examples"><tr><td><pre>i1 : matrix{{1,2,3},{4,5,6}}
o1 = | 1 2 3 |
| 4 5 6 |
2 3
o1 : Matrix ZZ <--- ZZ</pre>
</td></tr>
<tr><td><pre>i2 : R = QQ[x,y,z];</pre>
</td></tr>
<tr><td><pre>i3 : matrix{{x,0,2},{1,2,y}}
o3 = | x 0 2 |
| 1 2 y |
2 3
o3 : Matrix R <--- R</pre>
