# polyval

Version:

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

## Syntax

c = polyval(a, b)

## a

Coefficients in descending order of power of the polynomial you want to evaluate. a is a vector.

## b

Values at which you want to evaluate a. b is an array of any dimension.

## c

Evaluated values of a MathScript uses the following equation for calculating c: 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 b.

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