Kronecker delta calculator
Evaluate the discrete delta that tests whether indices agree.
How to use this calculator
Edit KroneckerDelta(3,3); equal indices give 1 and unequal indices give 0.
Tap the math below to edit it and see the result. Once a result is ready, press Tab on a hardware keyboard to accept it. Outside a matrix, Return completes the line; the phone math keyboard has the same Return action.

What to know
This discrete function is not the Dirac delta distribution.
Mathlean combines visual mathematical input with computation and canvas tools. Results depend on the expression and available engine support; check important answers independently.
