delta function

Generalized Kronecker Delta

Computes the Generalized Kronecker Delta.

delta(n, p = 1)

Arguments

• n: number of elements for each dimension.
• p: order of the generalized Kronecker delta, p=1 for the standard Kronecker delta.

Returns

array representing the generalized Kronecker delta tensor.

Examples

### Kronecker delta 3x3
delta(3)

### generalized Kronecker delta 3x3 of order 2
delta(3, p = 2)
