WebNov 30, 2024 · This paper presents effective methods based on different discrete transforms, such as Discrete Fourier Transform (DFT), Fractional Fourier Transform … WebMay 14, 2024 · Sorted by: 1. If you consider the set of n -by- n rotation matrices S O ( n) as a Lie group, then the corresponding Lie algebra is the set of antisymmetric or skew symmetric n -by- n matrices. I.e., in the limit of ϵ → 0, the any rotation matrix U is equal to I + ϵ T up to first-order. This is known as an "infinitessimal rotation".
