Evaluates the polynomial P(x) with matrix A. The data types you wire to the P(x) and A inputs determine the polymorphic instance to use.

Inputs/Outputs

  • c2ddbl.png A —

    A is a square matrix of real values. A acts as the independent variable of P(x). If A is not square, the VI sets P([A]) to an empty array and returns an error.

  • c1ddbl.png P(x) —

    P(x) contains the real polynomial coefficients in ascending order of power.

  • i2ddbl.png P([A]) —

    P([A]) returns the evaluation of the real polynomial P(x) at the real values A contains.

  • ii32.png error —

    error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

    • The VI evaluates the polynomial P(x) with the square matrix A. For example, the following polynomial defines the second-order polynomial described by the three-element array P[0…2]:

    P[2]x² + P[1]x + p[0]

    The evaluation of the preceding polynomial by the VI yields the following result:

    P([A]) = P[2]A² + P[1]A + P[0]I

    where I is the identity matrix and the same size as A.
