For example, the identity matrix (all zeroes except for ones on the diagonal) is given by the ith element of the jth row is the Kronecker delta of i and j.

Kronecker delta Is trivial.  It has two arguments.  If they're equal the result is 1.  If not the result is 0.

Sorry, I don't have any context.  I just saw the reference and reference to  Kroneker Delta.  I had not heard of it, so I even before I did research, I thought I would save time by asking this august panel.

Tom -

Can you provide a little more context?  The Kroneker Delta/Iverson Bracket is  a pretty fundamental and generally useful(used) abstraction across lots of domains.

If you are trying to use the tweeted advice you quoted, you must be working with "logical conditions and truth values in some formula"?   But that only narrows it down a little?

Who can tell us more about the Kronekernel Delta process and how, when, where it can be used?

The Iverson Bracket is a powerful generalization of the well known Kronecker Delta, very useful for embedding logical conditions and truth values into your formulas #Notation #MathType
