Detailed Description

BLAS Level 2 API.

tpmvStridedBatched performs one of the matrix-vector operations

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

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	[hipblasHandle_t] handle to the hipblas library context queue.
[in]	uplo	[hipblasFillMode_t] HIPBLAS_FILL_MODE_UPPER: A_i is an upper triangular matrix. HIPBLAS_FILL_MODE_LOWER: A_i is a lower triangular matrix.
[in]	transA	[hipblasOperation_t]
[in]	diag	[hipblasDiagType_t] HIPBLAS_DIAG_UNIT: A_i is assumed to be unit triangular. HIPBLAS_DIAG_NON_UNIT: A_i is not assumed to be unit triangular.
[in]	m	[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]	strideA	[hipblasStride] 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	[int] specifies the increment for the elements of one vector x.
[in]	stridex	[hipblasStride] stride from the start of one x_i vector to the next x_{i + 1}
[in]	batchCount	[int] The number of batched matrices/vectors.
