Declaration

func cblas_stbmv(_ ORDER: CBLAS_ORDER, _ UPLO: CBLAS_UPLO, _ TRANSA: CBLAS_TRANSPOSE, _ DIAG: CBLAS_DIAG, _ N: __LAPACK_int, _ K: __LAPACK_int, _ A: UnsafePointer<Float>?, _ LDA: __LAPACK_int, _ X: UnsafeMutablePointer<Float>?, _ 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') or the transpose of A ('T', 't', 'C', or 'c').

• DIAG:

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

• N:

  The order of matrix A.

• K:

  Half-bandwidth of matrix A.

• A:

  Triangular matrix A.

• LDA:

  The leading dimension of array containing matrix A.

• X:

  Vector x.

• INCX:

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

Discussion

Computes A*x and stores the results in x.
