detr

Arguments

h

double or polynomial or rational square matrix

Description

d=detr(h) returns the determinant d of the double or polynomial or rational function matrix h. Based on Leverrier's algorithm.

Examples

// Matrix of doubles
A = rand(5,5);
detr(A)

A = A+%i;
detr(A)

// Matrix of polynomials
x = poly(0, 'x')
A = [1+x 2 5; 3 4-x 3+x; x^2 1 x];
detr(A)

// Matrix of rationals
A = [1/x 2 3; 3 4/x 3/x; 1/x^2 1 1/x];
detr(A)
