characteristicpoly(A)
characteristicpoly(A,P)

The characteristicpoly command computes the characteristic polynomial of a matrix A. The result is returned as a vector of coefficients in ascending order. An optional second argument P specifies a modulus for the computation.

Examples

characteristicpoly([[1,2],[3,4]]);
	[-2, -5, 1]

characteristicpoly([[1,2],[3,4]],11);
	[9, 6, 1]
