Owning Class: polynomials

Requires: MathScript RT Module


c = polyval(a, b)


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



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.


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 b.


The following table lists the support characteristics of this function.

Supported in the LabVIEW Run-Time Engine Yes
Supported on RT targets Yes
Suitable for bounded execution times on RT Not characterized


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