• Eigenvalue
• Inclusion region
• Smallest singular value
• Lower bound

This paper presents a parameterized lower bound for the smallest singular value of a matrix based on a new Gersgorin-type inclusion region that has been established recently by these authors. The comparison of the new lower bound with known ones is supplemented with a numerical example.
