Detailed Description

BLAS Level 2 API.

trmv_strided_batched performs one of the matrix-vector operations

 x_i = A_i*x_i or x_i = A**T*x_i, 0 \le i < batch_count

where x_i is an n element vector and A_i is an n by n (unit, or non-unit, upper or lower triangular matrix) with strides specifying how to retrieve $x_i$ (resp. $A_i$) from $x_{i-1}$ (resp. $A_i$).

The vectors x_i are overwritten.

Parameters

[in]	handle	[rocblas_handle] handle to the rocblas library context queue.
[in]	uplo	[rocblas_fill] rocblas_fill_upper: A_i is an upper triangular matrix. rocblas_fill_lower: A_i is a lower triangular matrix.
[in]	transA	[rocblas_operation]
[in]	diag	[rocblas_diagonal] rocblas_diagonal_unit: A_i is assumed to be unit triangular. rocblas_diagonal_non_unit: A_i is not assumed to be unit triangular.
[in]	m	[rocblas_int] m specifies the number of rows of matrices A_i. m >= 0.
[in]	A	device pointer of the matrix A_0, of dimension ( lda, m )
[in]	lda	[rocblas_int] specifies the leading dimension of A_i. lda >= max( 1, m ).
[in]	stride_a	[rocblas_stride] stride from the start of one A_i matrix to the next A_{i + 1}
[in]	x	device pointer storing the vector x_0.
[in]	incx	[rocblas_int] specifies the increment for the elements of one vector x.
[in]	stride_x	[rocblas_stride] stride from the start of one x_i vector to the next x_{i + 1}
[in]	batch_count	[rocblas_int] The number of batched matrices/vectors.
