cblas_sspmv(_:_:_:_:_:_:_:_:_:_:)

Declaration

func cblas_sspmv(_ ORDER: CBLAS_ORDER, _ UPLO: CBLAS_UPLO, _ N: __LAPACK_int, _ ALPHA: Float, _ AP: UnsafePointer<Float>?, _ X: UnsafePointer<Float>?, _ INCX: __LAPACK_int, _ BETA: Float, _ Y: UnsafeMutablePointer<Float>?, _ INCY: __LAPACK_int)

Parameters

• ORDER:

  Specifies row-major (C) or column-major (Fortran) data ordering.

• UPLO:

  Specifies whether to use the upper or lower triangle from the matrix. Valid values are 'U' or 'L'.

• N:

  Order of matrix A and the number of elements in vectors x and y.

• ALPHA:

  Scaling factor that matrix A is multiplied by.

• AP:

  Matrix A (in packed storage format).

• X:

  Vector x.

• INCX:

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

• BETA:

  Scaling factor that vector y is multiplied by.

• Y:

  Vector y.

• INCY:

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

Discussion

Computes alpha*A*x + beta*y and stores the results in Y.
