  PLASMA_dsyr2k - Performs one of the symmetric rank 2k operations , or , 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 symmetric matrix and A and B are an n-by-k matrices the first case and k-by-n matrices 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: = PlasmaTrans:
  [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 A and B matrices with trans = PlasmaNoTrans. K specifies the number of rows of the A and B matrices with trans = PlasmaTrans.
  [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] | B | B is a LDB-by-kb matrix, where kb is K when trans = PlasmaNoTrans, and is N otherwise.
  [in] | LDB | The leading dimension of the array B. LDB must be at least max( 1, N ), otherwise LDB 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
