Declaration

func cblas_drot(_ N: __LAPACK_int, _ X: UnsafeMutablePointer<Double>?, _ INCX: __LAPACK_int, _ Y: UnsafeMutablePointer<Double>?, _ INCY: __LAPACK_int, _ C: Double, _ S: Double)

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:
