Creates the parameters used in the rot - Givens Rotation VI.

You can use a Givens rotation to zero the input y-component. The data types you wire to the x and y inputs determine the polymorphic instance to use.

Inputs/Outputs

  • ccdb.png x —

    x is the complex input x-component for the two-element vector.

  • ccdb.png y —

    y is the complex input y-coordinate for the two-element vector.

  • icdb.png r —

    r returns the x-coordinate after the Givens rotation.

  • idbl.png c —

    c returns the c parameter of the Givens rotation.

  • icdb.png s —

    s returns the s parameter of the Givens rotation.

  • ii32.png error —

    error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

  • icdb.png z —

    z returns the z parameter of the Givens rotation.

    Note You can use z to reconstruct Givens rotation parameters c and s.
