Function Syrk

* Rank-k update of symmetric matrix. (L3) Syrk(A, C, alpha=1.0, beta=0.0, uplo=PLower, trans=PNoTrans, n=-1, k=-1, ldA=max(1,A.Rows), ldC=max(1,C.Rows), offsetA=0, offsetB=0) PURPOSE C := alpha*A*A^T + beta*C, if trans is PNoTrans C := alpha*A^T*A + beta*C, if trans is PTrans C := alpha*

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