numerator
Numerator coefficients, in ascending order of power, of the rational polynomial.
This input accepts the following data types:

1D array of doubleprecision, floatingpoint numbers

1D array of complex doubleprecision, floatingpoint numbers
denominator
Denominator coefficients, in ascending order of power, of the rational polynomial.
This input accepts the following data types:

1D array of doubleprecision, floatingpoint numbers

1D array of complex doubleprecision, floatingpoint 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
normalized numerator
Normalized numerator coefficients, in ascending order of power, of the rational polynomial.
This output can return the following data types:

1D array of doubleprecision, floatingpoint numbers

1D array of complex doubleprecision, floatingpoint numbers
normalized denominator
Normalized denominator coefficients, in ascending order of power, of the rational polynomial.
This output can return the following data types:

1D array of doubleprecision, floatingpoint numbers

1D array of complex doubleprecision, floatingpoint numbers
error out

Algorithm for Normalizing Rational Polynomials with Lowest Denominator Term
The following equations define the numerator and denominator polynomials of a rational polynomial:
$\mathrm{numerator}=\sum _{i=0}^{n}{N}_{i}{x}^{i}$
$\mathrm{denominator}=\sum _{k=0}^{m}{D}_{k}{x}^{k}$
where
 n is the number of numerator coefficients in the rational polynomial
 m is the number of denominator coefficients in the rational polynomial
 N_{i} is the i^{th} numerator in the rational polynomial
 D_{k} is the k^{th} denominator in the rational polynomial
This node finds the lowest nonzero denominator D_{j} in the rational polynomial where D_{j} ≠ 0 and D_{j1} = D_{j2} = … = D_{1} = D_{0} = 0.
This node uses the following equation to normalize the numerator and denominator polynomials with D_{j}:
$\frac{\sum _{i=0}^{n}({N}_{i}\text{\hspace{0.17em}}/\text{\hspace{0.17em}}{D}_{j}){x}^{i}}{\sum _{k=0}^{m}({D}_{k}\text{\hspace{0.17em}}/\text{\hspace{0.17em}}{D}_{j}){x}^{k}}$
Where This Node Can Run:
Desktop OS: Windows
FPGA: Not supported
Web Server: Not supported in VIs that run in a web application
