Slice

Slice(A, I, n)

Returns the «n»th slice of array «A» along index «I».

The Slice function is so commonly used, as is its associational counterpart, the Subscript function, that a special shorthand notation is more often used in Analytica expressions. Slice(A, I, n) can be written as A[@I = n].

Slice(A, n)

When «A» is one-dimensional, «I» can be omitted. Use this syntax when you want to obtain the «n»th element of a list, but cannot name the index since it is implicit.

Examples

Index I := [10, 20, 30, 40]

Index J := ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']

Index K := 1..3

Variable A := Table(J)(9, 2, 3, 4, 1, 9, 0, 3)

Variable B := I + K

Slice(A, J, 5) → 1

Slice(A, J, 3..6) → [3, 4, 1, 9]

Slice(A, J, K) → Array(J, [9, 2, 3])

Slice(A, J, 8) → «null» {with an out-of-range warning}

Slice(A, I, 3) → Array(J, [9, 2, 3, 4, 1, 9, 0, 3])

Slice(B, I, 3) → Array(K,[31, 32, 33])

Slice(B, K, 3) → Array(I,[13, 23, 33, 43])

Slice(4, J, 5) → 4
