<title>CharPoly</title><br />
<short_description>characteristic polynomial of a matrix</short_description><br />
<br />
<description><br />
X is an indeterminate, and M is a square matrix whose entries do not involve X.<br />
<par/><br />
This function returns the characteristic polynomial of M in the indeterminate X.<br />
<br />
<example><br />
Use R ::= Q[x];<br />
CharPoly(Mat([[1,2,3],[4,5,6],[7,8,9]]), x);<br />
-x^3 + 15x^2 + 18x<br />
