Condition numbers for the truncated total least squares problem and their estimations

Qing-Le Meng, Huai-An Diao, Zheng-Jian Bai

In this paper, we present explicit expressions for the mixed and componentwise condition numbers of the truncated total least squares (TTLS) solution of $A\boldsymbol{x} \approx \b…

Backward Errors and Small Sample Condition Estimation for -Sylveter Equations

Huai-An Diao, Hong Yan, Eric King-wah Chu

In this paper, we adopt a componentwise perturbation analysis for -Sylvester equations. Based on the small condition estimation (SCE), we devise the algorithms to estimate n…
