How is the Heaviside function defined?

The Heaviside step function (named after physicist Oliver Heaviside) is a simple discontinuous piecewise function defined over the interval (-∞, ∞). The function, usually denoted as H(t), equals: 0 for all negative values of t, 1 for all positive values of t.

What is Heaviside function in Matlab?

The Heaviside function is a discontinuous function that returns 0 for x < 0 , 1/2 for x = 0 , and 1 for x > 0 .

Why is it called Heaviside?

The Heaviside layer, sometimes called the Kennelly–Heaviside layer, named after Arthur E. Kennelly and Oliver Heaviside, is a layer of ionised gas occurring roughly between 90km and 150 km (56 and 93 mi) above the ground — one of several layers in the Earth's ionosphere.
