Member of the polynomials class.

Syntax

c = polyval(a, b)

Description

Evaluates a polynomial at values you specify. This function works element-wise for matrices.

Examples

Inputs

Name	Description
a	Specifies the coefficients in descending order of power of the polynomial you want to evaluate. a is a vector.
b	Specifies the values at which you want to evaluate a. b is a matrix.

Outputs

Name	Description
c	Returns the evaluated values of a according to the following equation: c = a[1]*b^n+ ... +a[n]*b+a[n+1]*I, where n is the degree of a and I is the identity matrix. c is a matrix of the same size as a.

Examples

A = [1, 1, 1]
B = [1, 2; 3, 4]
C = polyval(A, B)
