PLASMA_dsyrk - Performs one of the hermitian rank k operations

\[ C = \alpha [ op( A ) \times g( op( A )' )] + \beta C \]

,

where op( X ) is one of

op( X ) = X or op( X ) = g( 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.

Parameters:
[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 ugate transposed: = PlasmaNoTrans: A is not transposed; = PlasmaTrans : A is 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 ), 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 ).
Returns:
Return values:
PLASMA_SUCCESS successful exit
