WebNov 13, 2024 · Spectral Python (SPy) is a pure Python module for processing hyperspectral image data (imaging spectroscopy data). It has functions for reading, displaying, manipulating, and classifying hyperspectral imagery. Full details about the package are on the web site. Installation Instructions WebJul 17, 2024 · Algorithm. The Fourier spectral methods are the most efficient numerical methods both in time and accuracy for solving PDEs in simple domains with a periodic boundary condition. They even achieve much higher accuracy with much smaller number of sampling points in comparison to finite differences and finite elements. bts fed u42 2021
