摘要：

Several extensions of the total least squares (TLS) method that are able to calculate a structured rank deficient approximation of a data matrix have been developed recently. The main result of this correspondence is the demonstration of the equivalence of two of these approaches, namely, the constrained total least squares (CLS) approach and the structured total least squares (STLS) approach. We also present a numerical comparison of both methods.
