roots
Roots for a polynomial.
If
roots
is empty, the node sets
polynomial
to 1.
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
Polynomial coefficients in ascending order of power.
This output can return the following data types:
-
1D array of double-precision, floating-point numbers

Error information.

Algorithm for Creating a Polynomial from Roots
This node uses the following equation to create a polynomial:
where
-
P(x) is the polynomial created from roots
-
x
is the variable of the polynomial
-
n
is the number of roots in the polynomial
-
r
i
is the
i
th
number of roots in the polynomial
-
P
i
is the
i
th
number of coefficients in the polynomial
Where This Node Can Run:
Desktop OS: Windows
FPGA:
Not supported
Web Server: Not supported in VIs that run in a web application
