Error control technique of quadrature-based algorithms for the action of real powers of a Hermitian positive-definite matrix

Motohiro Otsuka, Fuminori Tatsuoka, Tomohiro Sogabe +2

This study considers quadrature-based algorithms to compute $A^{α} b$ , the action of a real power of a Hermitian positive-definite matrix $A$ on a vector $ \boldsymbol{b}…

Observed-unobserved information transfer in ensemble Kalman filtering for the partially observed Lorenz 96 model

Kota Takeda

We consider filtering problems with partial observations of nonlinear dynamical systems, where accurate state estimation relies on information transfer from observed to unobserved…
