heaviside
Computes the Heaviside step function.
Nerdamer uses the half-maximum convention: the result is 0 for negative inputs, 1/2 at zero, and 1 for positive inputs. Symbolic inputs remain as heaviside(x) unless assumptions determine their sign.
Examples
These examples use Nerdamer Notation.
Evaluate a negative argument.
heaviside(-2) // → 0
Use the half-maximum value at zero.
heaviside(0) // → 1/2
Evaluate a positive argument.
heaviside(3) // → 1
