x
xcomponent for the twoelement vector.
This input accepts the following data types:

Doubleprecision, floatingpoint numbers

Complex doubleprecision, floatingpoint numbers
Default: The default value is 0 if x is a doubleprecision, floatingpoint number. The default value is 0+0i if x is a complex doubleprecision, floatingpoint number.
y
ycomponent for the twoelement vector.
This input accepts the following data types:

Doubleprecision, floatingpoint numbers

Complex doubleprecision, floatingpoint numbers
Default: The default value is 0 if y is a doubleprecision, floatingpoint number. The default value is 0+0i if y is a complex doubleprecision, floatingpoint number.
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
r
xcomponent after the Givens rotation.
This output can return the following data types:

Doubleprecision, floatingpoint numbers

Complex doubleprecision, floatingpoint numbers
c
c parameter of the Givens rotation.
s
s parameter of the Givens rotation.
This output can return the following data types:

Doubleprecision, floatingpoint numbers

Complex doubleprecision, floatingpoint numbers
error out
Error information.

z
z parameter of the Givens rotation.
You can use this output to reconstruct Givens rotation parameters c and s.
This output can return the following data types:

Doubleprecision, floatingpoint numbers

Algorithm for Calculating Givens Rotation Parameters
This node uses the following equations to calculate Givens rotation parameters:
$\left[\begin{array}{cc}c& s\\ s& c\end{array}\right]*\left[\begin{array}{c}x\\ y\end{array}\right]=\left[\begin{array}{c}r\\ 0\end{array}\right]$
c^{2} + s^{2} = 1
where
 x is the xcomponent of the twoelement vector
 y is the ycomponent of the twoelement vector
 s and c are the Givens rotation parameters
