4.6 NUMERICAL CONSIDERATIONS
m
Define C = [ A ; b ]
× ( n + 1 ) and consider the (one-dimensional) TLS solu-
tion. The total number of operations (flops) required by TLS EXIN after the
presentation of all the rows of C is given by 2 m ( 3 n + 1 ) . The ratio k ( m , n ) of
the operation counts of the partial SVD (see [98, p. 146] with s = 2 [76], where
