cblas_csrot(_:_:_:_:_:_:_:)

Applies a Givens rotation matrix to a pair of complex vectors.

Declaration

func cblas_csrot(_ N: __LAPACK_int, _ X: OpaquePointer?, _ INCX: __LAPACK_int, _ Y: OpaquePointer?, _ INCY: __LAPACK_int, _ C: Float, _ S: Float)

Parameters

  • N:

    The number of elements in vectors X and Y.

  • X:

    Vector X. Modified on return.

  • INCX:

    Stride within X. For example, if incX is 7, every 7th element is used.

  • Y:

    Vector Y. Modified on return.

  • INCY:

    Stride within Y. For example, if incY is 7, every 7th element is used.

  • C:

    The value cos(θ) in the Givens rotation matrix.

  • S:

    The value sin(θ) in the Givens rotation matrix.
