I Dirac Delta Function
“delta” is the Dirac Delta function. The delta function evaluates numerically as shown below.
0, x x 0
D(x) =
{
D( x ), x = 0
Non-numeric expressions passed to the delta function are left unevaluated. The integral of a
linear delta function is a Heaviside function.
Syntax: delta( x )
x : variable or number
Examples:
I n th Delta Function
The n th -delta function is the n th differential of the delta function.
Syntax: delta( x , n )
x : variable or number
n : number of differentials
Examples:
2-4-16
