Detailed Description
The TRTRI functions invert a triangular n-by-n matrix A.
A can be upper or lower triangular, depending on the value of uplo, and unit or non-unit triangular, depending on the value of diag.
- Parameters
-
[in] handle - rocblas_handle. [in] uplo - rocblas_fill. Specifies whether the upper or lower part of the matrix A is stored. If uplo indicates lower (or upper), then the upper (or lower) part of A is not used. [in] diag - rocblas_diagonal. If diag indicates unit, then the diagonal elements of A are not referenced and assumed to equal one. [in] n - rocblas_int. n >= 0. The number of rows and columns of the matrix A. [in,out] A - pointer to type. Array on the GPU of dimension lda*n. On entry, the triangular matrix. On exit, the inverse of A if info = 0. [in] lda - rocblas_int. lda >= n. Specifies the leading dimension of A. [out] myInfo - pointer to a rocblas_int on the GPU. If info = 0, successful exit. If info = i > 0, A is singular. A[i,i] is the first zero element in the diagonal.
