Calculates the partial fraction expansion of a rational polynomial using the Heaviside cover-up method.

Numerator coefficients, in ascending order of power, of the rational polynomial.

Denominator coefficients, in ascending order of power, for the rational polynomial.

Level of tolerance to use when this node determines if the roots in the denominator polynomial are unique or repeated.

**Default: **1E-05

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

Coefficients, in ascending order of power, for the quotient polynomial that results from the division of the numerator polynomial by the denominator polynomial.

Unique roots of the denominator polynomial.

The roots of the denominator polynomial result from removing all common factors between the numerator polynomial and the denominator polynomial.

Numerators of the partial fractions that result for each pole.

Number of times each unique root in the denominator polynomial occurs.

Multiplicity occurs when the difference between two elements in **poles** is less than **tolerance**.
