Detailed Description
BLAS Level 2 API.
tpmv performs one of the matrix-vector operations
x = A*x or x = A**T*x,
where x is an n element vector and A is an n by n unit, or non-unit, upper or lower triangular matrix, supplied in the pack form.
The vector x is overwritten.
- Parameters
-
[in] handle [rocblas_handle] handle to the rocblas library context queue. [in] uplo [rocblas_fill] rocblas_fill_upper: A is an upper triangular matrix. rocblas_fill_lower: A is a lower triangular matrix. [in] transA [rocblas_operation] [in] diag [rocblas_diagonal] rocblas_diagonal_unit: A is assumed to be unit triangular. rocblas_diagonal_non_unit: A is not assumed to be unit triangular. [in] m [rocblas_int] m specifies the number of rows of A. m >= 0. [in] A device pointer storing matrix A, of dimension at leat ( m * ( m + 1 ) 2 ). Before entry with uplo = rocblas_fill_upper, the array A must contain the upper triangular matrix packed sequentially, column by column, so that A[0] contains a_{0,0}, A[1] and A[2] contain a_{0,1} and a_{1, 1} respectively, and so on. Before entry with uplo = rocblas_fill_lower, the array A must contain the lower triangular matrix packed sequentially, column by column, so that A[0] contains a_{0,0}, A[1] and A[2] contain a_{1,0} and a_{2,0} respectively, and so on. Note that when DIAG = rocblas_diagonal_unit, the diagonal elements of A are not referenced, but are assumed to be unity. [in] x device pointer storing vector x. [in] incx [rocblas_int] specifies the increment for the elements of x. incx must not be zero.
