A note on estimates for the spectral radius of a nonnegative matrix
Shi-Ming Yang, Ting‐Zhu Huang · Electronic Journal of Linear Algebra · 2005
Utilizing the concept of Perron complement, a new estimate for the spectral radius of a nonnegative irreducible matrix is presented. A new matrix is derived that preserves the spectral radius while its minimum row sum increases and its maximum row sum decreases. Numerical examples are provided to illustrate the effectiveness of this approach.
