Last Modified: March 15, 2017

Creates a polynomial with roots represented by an input vector or computes the characteristic polynomial of an input matrix.

## Syntax

p = poly(z)

## z

Real or complex array of any dimension. If z is a matrix, z must be square. If z is an array, MathScript first flattens the array before creating a polynomial input.

## p

Coefficients in descending order of power of the polynomial with roots of z. If z is a matrix, p returns the coefficients in descending order of power of the characteristic polynomial of z. p is a real or complex vector.

Z = [1, 2, 3, 4];
P = poly(Z)
