Level 3 BLAS like routine for C in RFP Format. SFRK: 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 real 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.
