Module SSYRK in IMSLM

General Information

Performs one of the symmetric rank k operations C = alpha*A*trans(A) + beta*C, or C = alpha*trans(A)*A + beta*C, where alpha and beta are scalars, C is an n by n symmetric matrix and A is an n by k matrix in the first case and a k by n matrix in the second case. Trans represents the transpose of the matrix.
