## Detailed Description

BLAS Level 2 API.

tpmv_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] 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.
