Data Matrices Containing Mode Energies of Fermi-Pasta-Ulam-Tsingou model $\beta$ with $N=32$

The datasets contain the energy modes of the FPUT $\beta$ model with $N = 32$ coupled harmonic oscillators, computed for various values of $\beta$, using an initial condition that excites either the first mode ($k = 1$, $A = 10$) or the second mode ($k = 2$, $A = 10$). The columns of each energy data matrix correspond to the time-evolution of energy modes with $k=1, 2, \cdots 32$. Some energy modes under scrutiny are shown in Figs. 1, 2, 10, 11, 12, 13 of preprint: arXiv:2411.02058 (arXiv).
