Many model diffraction problems, generated by the Helmholtz equation, can be reduced to solving the infinite systems of linear algebraic equations SX s F. It proves that often the operators S in these problems satisfy some operator identities of the form AS y SB s βΈ βΈ U , where A and B are diagonal
## Abstract In this paper, an extension of the structured total leastβsquares (STLS) approach for __nonβlinearly structured__ matrices is presented in the soβcalled βRiemannian singular value decompositionβ (RiSVD) framework. It is shown that this type of STLS problem can be solved by solving a set
