Oliver Heaviside FRS was an English self-taught mathematician and physicist who invented a new technique for solving differential equations (equivalent to the Laplace transform), independently developed vector calculus, and rewrote Maxwell's equations in the form commonly used today. He significantly shaped the way Maxwell's equations are understood and applied in the decades follo… WebWhat is PyWavelets. PyWavelets is a free Open Source library for wavelet transforms in Python.
