Detailed Description
LASWP performs a series of row interchanges on the matrix A.
Row interchanges are done one by one. If \(\text{ipiv}[k_1 + (j - k_1) \cdot \text{abs}(\text{incx})] = r\), then the j-th row of A will be interchanged with the r-th row of A, for \(j = k_1,k_1+1,\dots,k_2\). Indices \(k_1\) and \(k_2\) are 1-based indices.
- Parameters
-
[in] handle rocblas_handle. [in] n rocblas_int. n >= 0.
The number of columns of the matrix A.[in,out] A pointer to type. Array on the GPU of dimension lda*n.
On entry, the matrix to which the row interchanges will be applied. On exit, the resulting permuted matrix.[in] lda rocblas_int. lda > 0.
The leading dimension of the array A.[in] k1 rocblas_int. k1 > 0.
The k_1 index. It is the first element of ipiv for which a row interchange will be done. This is a 1-based index.[in] k2 rocblas_int. k2 > k1 > 0.
The k_2 index. k_2 - k_1 + 1 is the number of elements of ipiv for which a row interchange will be done. This is a 1-based index.[in] ipiv pointer to rocblas_int. Array on the GPU of dimension at least k_1 + (k_2 - k_1)*abs(incx).
The vector of pivot indices. Only the elements in positions k_1 through k_1 + (k_2 - k_1)*abs(incx) of this vector are accessed. Elements of ipiv are considered 1-based.[in] incx rocblas_int. incx != 0.
The distance between successive values of ipiv. If incx is negative, the pivots are applied in reverse order.
