Title:
PROCESSING DEVICE, PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/039056
Kind Code:
A1
Abstract:
A processing device (200) derives a displacement vector u on the basis of an inverse matrix H-1 of an operator matrix H, which represents an operator for displacement as a matrix, and an acceleration vector y. The operator matrix H is represented using a first term having a first matrix h. The first matrix h is a square matrix of N rows and N columns for using a difference method to perform second-order time differentiation that imposes a periodic boundary condition on the displacement vector u. The periodic boundary condition is a condition that displacements in periods before and after a period in which time series data of a displacement u is to be derived have the same value as the time series data of the displacement.
