CORE_slauum - Computes the product U * U' or L' * L, where the triangular factor U or L is stored in the upper or lower triangular part of the array A.
If UPLO = 'U' or 'u' then the upper triangle of the result is stored, overwriting the factor U in A. If UPLO = 'L' or 'l' then the lower triangle of the result is stored, overwriting the factor L in A.
[in] | uplo | = PlasmaUpper: Upper triangle of A is stored; = PlasmaLower: Lower triangle of A is stored. |
[in] | N | The order of the triangular factor U or L. N >= 0. |
[in,out] | A | On entry, the triangular factor U or L. On exit, if UPLO = 'U', the upper triangle of A is overwritten with the upper triangle of the product U * U'; if UPLO = 'L', the lower triangle of A is overwritten with the lower triangle of the product L' * L. |
[in] | LDA | The leading dimension of the array A. LDA >= max(1,N). |
