Function: dirac (x) ¶

Compute the Dirac delta (generalized) function.

The Dirac delta “function” is a generalized function (or distribution) which is zero almost everywhere, except at the origin where it is infinite.

Examples:

dirac (0)
  ⇒ Inf
dirac (1)
  ⇒ 0
dirac ([-10 -1 0 1 inf])
  ⇒ 0     0   Inf     0     0
