Implementation of the Kronecker delta and Dirac delta functions
This module implements the following methods:
kronecker_delta(i, j)
: Discrete analog of Dirac delta function δij for integersi
andj
dirac_delta(x)
: Dirac delta function δ(x) defined along the real number line:
dirac_delta_integral(lowerBound, upperBound)
: Integral of the Dirac delta function: ∫ δ(x) dx fromlowerBound
toupperBound
(Returns the indefinite integral from -∞ to +∞ when no arguments given)
nascent-delta(a, x)
: Evaluates ηa(x), a function within a sequence of zero-centered normal distributions
nascent-delta-integral(a, lowerBound, upperBound)
: Integral of the nascent delta function: ∫ η(x) dx fromlowerBound
toupperBound
(Returns the indefinite integral from -∞ to +∞ when no arguments given)
