Tests whether two values are equal. Returns 1 if number1 = number2; returns 0 otherwise. Use this function to filter a set of values. For example, by summing several DELTA functions you calculate the count of equal pairs. This function is also known as the Kronecker Delta function. Syntax...

Peter Szekeres, A Course in Modern Mathematical Physics, Cambridge, 2004, Chapter 12: Distributions 数学上来看,Dirac于1926年引入了这个不讲武德的“函数”。很快啊!收获一大批数学家或者数学学得好的人的攻击。John von Neumann就立即反击,写了本“量子力学的数学基础”,可以完全回避掉delta 函数。但是到了19...
The delta function is a generalized function that can be defined as the limit of a class of delta sequences. The delta function is sometimes called "Dirac's delta function" or the "impulse symbol" (Bracewell 1999). It is implemented in the Wolfram Langua
The integral of the delta-function is 1, but when does "1" have to be interpreted as an integral of the delta-function? In order to make an interpretation of the volumes of figures of different dimensions more homogeneous, we follow a line of thought that leads us "back" to the ...
