Eigenvalues and Singular Values of Dual Quaternion Matrices
Liqun Qi, Ziyan Luo
The poses of robotics in time points may be represented by an dual quaternion matrix. In this paper, we study the spectral theory of dual quaternion matrices.…
Eigenvalues and Singular Value Decomposition of Dual Complex Matrices
Liqun Qi, Ziyan Luo
We introduce right eigenvalues and subeigenvalues for square dual complex matrices. An dual complex Hermitian matrix has exactly right eigenvalues and subeigenvalu…
A Note on Quaternion Skew-Symmetric Matrices
Liqun Qi, Ziyan Luo
The product of a complex skew-symmetric matrix and its conjugate transpose is a positive semi-definite Hermitian matrix with nonnegative eigenvalues, with a property that each dist…
Tubal Matrices
Liqun Qi, Ziyan Luo
It was shown recently that the f-diagonal tensor in the T-SVD factorization must satisfy some special properties. Such f-diagonal tensors are called s-diagonal tensors. In this pap…
Computing One-bit Compressive Sensing via Double-Sparsity Constrained Optimization
Shenglong Zhou, Ziyan Luo, Naihua Xiu +1
One-bit compressive sensing gains its popularity in signal processing and communications due to its low storage costs and low hardware complexity. However, it has been a challengin…
