Detailed Description

--------------— syrk, herk ---------------— performs one of the symmetric rank k operations

\[ C := \alpha A A^T + \beta C, \]

or

\[ C := \alpha A^T A + \beta*C \]

where \(\alpha\) and \(\beta\) are scalars, C is an \(n\times n\) symmetric matrix and A is an \(n\times k\) matrix in the first case and a \(k\times n\) matrix in the second case.
