syrk performs a rank-n update of an n-by-n symmetric matrix c, that is, one of the following operations:
c := alpha*a*a' + beta*c  for trans = 'N'or'n'
c := alpha*a'*a + beta*c  for trans = 'T'or't','C'or'c',
where c is an n-by-n symmetric matrix;
a is an n-by-k matrix, if trans = 'N'or'n',
a is a k-by-n matrix, if trans = 'T'or't','C'or'c'.

syrk performs a rank - n update of an n - by - n symmetric matrix c that is one of the following operations : c : = alpha * a * a + beta * c for trans = N or n c : = alpha * a * a + beta * c for trans = T or t C or c where c is an n - by - n symmetric matrix ; a is an n - by - k matrix if trans = N or n a is a k - by - n matrix if trans = T or t C or c .
