cblas_dtpmv(_:_:_:_:_:_:_:_:)

Declaration

func cblas_dtpmv(_ ORDER: CBLAS_ORDER, _ UPLO: CBLAS_UPLO, _ TRANSA: CBLAS_TRANSPOSE, _ DIAG: CBLAS_DIAG, _ N: __LAPACK_int, _ AP: UnsafePointer<Double>?, _ X: UnsafeMutablePointer<Double>?, _ INCX: __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'.

• TRANSA:

  Specifies whether to use matrix A ('N' or 'n'), the transpose of A ('T' or 't'), or the conjugate of A ('C' or 'c').

• DIAG:

  Specifies whether the matrix is unit triangular. Possible values are 'U' (unit triangular) or 'N' (not unit triangular).

• N:

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

• AP:

  Matrix A.

• X:

  Vector x.

• INCX:

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

Discussion

Computes A*x, A, or conjg(A and stores the results in X.
