cblas_ztbmv(_:_:_:_:_:_:_:_:_:_:)
Scales a triangular band matrix, then multiplies by a vector (double-precision complex).
Declaration
func cblas_ztbmv(_ ORDER: CBLAS_ORDER, _ UPLO: CBLAS_UPLO, _ TRANSA: CBLAS_TRANSPOSE, _ DIAG: CBLAS_DIAG, _ N: __LAPACK_int, _ K: __LAPACK_int, _ A: OpaquePointer?, _ LDA: __LAPACK_int, _ X: OpaquePointer?, _ 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:
Matrix
A. - LDA:
The leading dimension of array containing matrix
A. - X:
Vector
x. - INCX:
Stride within
X. For example, ifincXis 7, every 7th element is used.
Discussion
Computes A*x and stores the results in x.
