[in,out] | descA | The descriptor of the matrix A to permute. |
[in] | i1 | The first element of IPIV for which a row interchange will be done. |
[in] | i2 | The last element of IPIV for which a row interchange will be done. |
[in] | ipiv | The pivot indices; Only the element in position i1 to i2 are accessed. The pivot are offset by A.i. |
[in] | inc | The increment between successive values of IPIV. If IPIV is negative, the pivots are applied in reverse order. |
[in] | Akk | The triangular matrix Akk. The leading descA.nb-by-descA.nb lower triangular part of the array Akk contains the lower triangular matrix, and the strictly upper triangular part of A is not referenced. The diagonal elements of A are also not referenced and are assumed to be 1. |
[in] | ldak | The leading dimension of the array Akk. ldak >= max(1,descA.nb). |
