9201105 Plemmons Two undergraduate students will be involved in this project. One of them will work on developing iterative methods for linear estimation in signal processing. The work includes developing effective FFT-based preconditioners for conjugate gradient iterative algorithms. The other student will study matrix eigenvalue methods in the adaptive control of deformable mirrors. Matrix computations play an important role in aero-optics applications for astronomical and aero-optic imaging. Numerical experimentation will be undertaken, using data from an astronomical facility. ***

9201105 Plemmons两名本科生将参与这个项目。其中一人将致力于开发信号处理中线性估计的迭代方法。工作包括为共轭梯度迭代算法开发有效的基于FFT的预条件子。另一个学生将学习变形镜自适应控制中的矩阵特征值方法。矩阵计算在气动光学的天文和气动光学成像应用中起着重要的作用。将利用来自天文设施的数据进行数值实验。***
