Iterative Refinement for a Subset of Eigenvectors of Symmetric Matrices via Matrix Multiplications

Takeshi Terao, Katsuhisa Ozaki, Toshiyuki Imamura +1

We develop an iterative refinement method that improves the accuracy of a user-chosen subset of eigenvectors () of an real symmetric matrix. Using an orthog…

Error Analysis of Matrix Multiplication Emulation Using Ozaki-II Scheme

Yuki Uchino, Katsuhisa Ozaki, Toshiyuki Imamura

The Ozaki-II scheme is an emulation method that leverages the Chinese Remainder Theorem to compute high-precision matrix multiplication via a sequence of low-precision matrix multi…
