Remove Zero Coefficients (G Dataflow)

Coefficients, in ascending order of power, of a real polynomial.

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 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.

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

Level at which the node removes the trailing elements from the polynomial coefficients.

The node removes the trailing elements whose absolute values or relative values are less than or equal to threshold. If all the elements in polynomial in are less than or equal to threshold, polynomial out returns a one-element array that contains the first element of polynomial in.

Default: 0

Method to remove the trailing elements from the polynomial coefficients.

Default: Absolute Value

Coefficients of the real polynomial after removing the trailing coefficients near zero.

This output can return the following data types:

• 1D array of double-precision, floating-point numbers
• 1D array of complex double-precision, floating-point numbers

Number of trailing near-zero coefficients that this node removed.
