Uses partial fraction expansion (PFE) to reconstruct a rational polynomial.
Coefficients, in ascending order of power, for the quotient polynomial.
Use the Partial Fraction Expansion node to obtain polynomial.
Unique roots of the denominator polynomial.
Use the Partial Fraction Expansion node to obtain poles.
Numerators of the partial fractions that result for each pole.
Use the Partial Fraction Expansion node to obtain residues.
Number of times each unique root in the denominator polynomial occurs.
Use the Partial Fraction Expansion node to obtain multiplicity. If multiplicity is empty, this node calculates the number of nonzero elements in each row of residues and regards that number as the multiplicity of the corresponding pole.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
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.
Default: No error
Method this node uses to handle the co-factors of the numerator and denominator polynomials.
Name | Value | Description |
---|---|---|
Cancel Co-factors | 0 | Computes the greatest common denominator (GCD) for the numerator and denominator polynomials before returning the output data. |
Reserve Co-factors | 1 | Keeps the numerator and denominator polynomial unchanged and returns the output data directly. |
Default: Cancel Co-factors
Numerator coefficients, in ascending order of power, of the rational polynomial.
Denominator coefficients, in ascending order of power, of the rational polynomial.
