CORE_cherk - Performs one of the hermitian rank k operations
\[ C = \alpha [ op( A ) \times conjfg( op( A )' )] + \beta C \]
,
where op( X ) is one of
op( X ) = X or op( X ) = conjfg( X' )
where alpha and beta are real scalars, C is an n-by-n hermitian matrix and A is an n-by-k matrix in the first case and a k-by-n matrix in the second case.
[in] | uplo | = PlasmaUpper: Upper triangle of C is stored; = PlasmaLower: Lower triangle of C is stored. |
[in] | trans | Specifies whether the matrix A is transposed or conjfugate transposed: = PlasmaNoTrans: A is not transposed; = PlasmaConjTrans: A is conjfugate transposed. |
[in] | N | N specifies the order of the matrix C. N must be at least zero. |
[in] | K | K specifies the number of columns of the matrix op( A ). |
[in] | alpha | alpha specifies the scalar alpha. |
[in] | A | A is a LDA-by-ka matrix, where ka is K when trans = PlasmaNoTrans, and is N otherwise. |
[in] | LDA | The leading dimension of the array A. LDA must be at least max( 1, N ) if trans == PlasmaNoTrans, otherwise LDA must be at least max( 1, K ). |
[in] | beta | beta specifies the scalar beta |
[in,out] | C | C is a LDC-by-N matrix. On exit, the array uplo part of the matrix is overwritten by the uplo part of the updated matrix. |
[in] | LDC | The leading dimension of the array C. LDC >= max( 1, N ). |
