The Journal of Machine Learning Research 2024年 第1期25卷 3284-3339页
作者: Juan-Pablo Ortega Daiying Yin Division of Mathematical Sciences Nanyang Technological University Singapore
A complete structure-preserving learning scheme for single-input/single-output (SISO) linear port-Hamiltonian systems is proposed. The construction is based on the solution, when possible, of the unique identification... 详细信息

Numerical Methods to Solve the Complex Symmetric Stabilizing Solution of the Complex Matrix Equation X+ATX-1A =Q
收藏 引用
数学研究 2015年 第1期48卷 53-65页
作者: Yao Yao Xiao-Xia Guo School of Mathematical Sciences Ocean University of China Qingdao 266100Shandong P.R.China
When the matrices $A$ and $Q$ have special structure, the structure-preservingalgorithm was used to compute the stabilizing solution of the complex matrix equation $X+A^TX^{-1}A=Q.$ In this paper, we study the numeric... 详细信息
