。我们应用最新的计算矩阵联合谱特性的方法来找到 N ≤ 20 阶 Daubechies 小波的 H°older 指数的精确值。还分析了这些小波的局部规律性。特别是,我们找到了局部规律性最差的点。在所有情况下,它们都是理性的,但并不总是二元的。
. We apply recent methods of computing the joint spectral characteristics of matrices to find precise values of the H¨older exponents of Daubechies wavelets of order N ≤ 20. The local regularity of these wavelets is also analyzed. In particular, we find the points of the worst local regularity. In all cases they are rational, but not always dyadic.
