Function Syr2k

* Rank-2k update of symmetric matrix. (L3) syr2k(A, B, C, alpha, beta, uplo=PLower, trans=PNoTrnas, n=-1, k=-1, ldA=max(1,A.Rows), ldB=max(1,B.Rows), ldC=max(1,C.Rows), offsetA=0, offsetB=0, offsetC=0) PURPOSE C := alpha*(A*B^T + B*A^T) + beta*C, if trans is NoTrans C := alpha*(A^T*B + B^

(A, B, C matrix.Matrix, alpha, beta matrix.Scalar, opts ...linalg.Option)
