This section lists corrections and corrections for misprints in the book "Rank-Deficient and Discrete Ill-Posed Problems" as of March 27, 2011. The corrections are categorized into two groups: those present in both the first and second printings, and those specific to the first printing only. **Misprints in Both First and Second Printings:** - Page 59: Equation (3.37) should replace $(\begin{array}{cc} R_{11}^{-1} & 0 \\ 0 & 0 \end{array})^{\mathrm{T}}$ with $(\begin{array}{cc} R_{11}^{-1} & 0 \\ 0 & 0 \end{array})$. - Page 83: Equation (4.34) should change $u_{i}^{T} b$ to $u_{j}^{T} b$. - Page 86: Line 4 from the bottom should change $\sigma_{0}^{2}(\sum_{i=1}^{p} \frac{\gamma_{i}}{\gamma_{i}^{2}+\lambda^{2}})^{2}$ to $\sigma_{0}^{2} \sum_{i=1}^{p}(\frac{\gamma_{i}}{\gamma_{i}^{2}+\lambda^{2}})^{2}$. - Page 87: Line 6 from the top should change $\ell \sigma_{0} /(s \lambda)$ to $\ell \sigma_{0} /(2 \lambda)$. - Page 95: Line 1 below the figure caption should change $10^{-1}$ to $5 \cdot 10^{-3}$. - Page 102: A "0" is missing in the illustration of the annihilation process. - Page 147: Caption for Fig. 6.2 should change $\sigma_{i}$ to $\sigma_{i}^{2}$. - Page 184: Line 1 below Eq. (7.17) should change “Fig. 7.2 (p. 196)” to “Fig. 7.1 (p. 194)”. **Misprints Only in the First Printing:** - Page 8: Line 17 from the top should change $0, \ldots, q$ to $0, \ldots, p$. - Page 38: Lines 14–16 should replace “A suite of [...] from the author.” with “A MATLAB package with routines for computing and modifying rank-revealing decompositions, called UTV Tools, was published in [379].” - Page 43: Equation (2.52) should change $\|A\This section lists corrections and corrections for misprints in the book "Rank-Deficient and Discrete Ill-Posed Problems" as of March 27, 2011.
