A
Square matrix of values.
A
acts as the independent variable of
polynomial. If
A
is not square, the node sets
polynomial evaluation
to an empty array and returns an error.
This input accepts the following data types:
-
2D array of double-precision, floating-point numbers
-
2D array of complex double-precision, floating-point numbers
polynomial
Polynomial coefficients in ascending order of power.
This input accepts the following data types:
-
1D array of double-precision, floating-point numbers
-
1D array of complex double-precision, floating-point numbers
error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Many nodes provide an
error in
input and an
error out
output so that the node can respond to and communicate errors that occur while code is running. The value of
error in
specifies whether an error occurred before the node runs. Most nodes respond to values of
error in
in a standard, predictable way.
error in
does not contain an error

error in
contains an error

If no error occurred before the node runs, the node begins execution normally.
If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as
error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the
error in
value as
error out.

Default:
No error
polynomial evaluation
Evaluation of the polynomial at the values in
A.
This output can return the following data types:
-
2D array of double-precision, floating-point numbers
-
2D array of complex double-precision, floating-point numbers
error out
Error information.
The node produces this output according to standard error behavior.

error out
output so that the node can respond to and communicate errors that occur while code is running. The value of

Algorithm for Evaluating a Polynomial with Matrix
This node 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]:
The evaluation of the preceding polynomial by the node yields the following result:
where
I
is the identity matrix and the same size as
A.
