cblas_dsyr(_:_:_:_:_:_:_:_:)

Declaration

func cblas_dsyr(_ ORDER: CBLAS_ORDER, _ UPLO: CBLAS_UPLO, _ N: __LAPACK_int, _ ALPHA: Double, _ X: UnsafePointer<Double>?, _ INCX: __LAPACK_int, _ A: UnsafeMutablePointer<Double>?, _ LDA: __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; number of elements in vector x.

• ALPHA:

  Scaling factor to multiply x by.

• X:

  Vector x.

• INCX:

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

• A:

  Matrix A.

• LDA:

  Leading dimension of array containing matrix A.

Discussion

Calculates A + alpha*x*x and stores the result in A.
