aeye

Purpose

Creates an N-dimensional array in which the planes described by the two trailing dimensions of the array are equal to the identity.

Format

a = aeye(ord)
Parameters:ord (Nx1 vector of orders) – the sizes of the dimensions of a.
Returns:a (N-dimensional array) – containing 2-dimensional identity arrays.

Examples

v = { 2, 3, 3 };
a = aeye(v);

a will be a 2x3x3 array, such that: [1,1,1] through [1,3,3] =

1 0 0
0 1 0
0 0 1

[2,1,1] through [2,3,3] =

1 0 0
0 1 0
0 0 1

Remarks

If ord contains numbers that are not integers, they will be truncated to integers.

The planes described by the two trailing dimensions of a will contain 1’s down the diagonal and 0’s everywhere else.
