- Abstract:
- It is given that a simplistic proof for the solvability of Total Least Squares problem, extending this idea for General Total Least Squares problem, establishes a sufficient and necessary condition for solvability, proves the uniqueness of the amendment matrix and gives it's expression.
- Key words:
- general total least squares problem; SVD decomposition; singular values; singular vectors
