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.
