Inmathematics, theKronecker deltaorKronecker's delta, named afterLeopold Kronecker, is afunctionof twovariables, usuallyintegers. The function is 1 if the variables are equal, and 0 otherwise: where Kronecker delta δijis apiecewisefunction of variables and . For example, δ1 2= 0, whereas δ...
For kroneckerDelta with numeric inputs, use the eq function instead. Set symbolic variable m equal to symbolic variable n and test their equality using kroneckerDelta. syms m n m = n; kroneckerDelta(m,n) ans = 1 kroneckerDelta returns 1 indicating that the inputs are equal. Compare symbol...

The simplest interpretation of the Kronecker delta is as the discrete version of the delta function defined by delta_(ij)={0 for i!=j; 1 for i=j. (1) The Kronecker delta is implemented in the Wolfram Language as KroneckerDelta[i, j], as well as i
The Dirac delta can be loosely thought of as a function on the real line which is zero everywhere except at the origin, where it is infinite, and which is also constrained to satisfy the identity [18] This is merely aheuristiccharacterization. The Dirac delta is not a function in the tra...

where 1A(·) is an indicator function of A. Thus if a Dirac delta in (2) is conceptualized as modeling an idealized point-mass at x then δx(dx) represents the “mass” contained in an infinitesimal set dx. Note that (3) is a simplified representation of a “measure” and the alter...
