slice

..  slice(A, inds...)

Returns a view of array ``A`` with the given indices like :func:`sub`, but drops all dimensions indexed with scalars.

Examples

The slice function in Julia returns a view of the array A with the given indices, similar to the sub function. However, it drops all dimensions indexed with scalars.

julia> A = [1 2 3; 4 5 6; 7 8 9]
3×3 Array{Int64,2}:
 1  2  3
 4  5  6
 7  8  9

julia> slice(A, 1:2, 2:3)
2×2 Array{Int64,2}:
 2  3
 5  6

In this example, the slice function is used to create a view of array A using the indices 1:2 for rows and 2:3 for columns. The resulting view is a 2x2 array containing the selected elements.

Note that the slice function drops any dimensions indexed with scalars. This means that if a single index is provided for a particular dimension, that dimension is removed from the resulting view.

julia> A = [1 2 3; 4 5 6; 7 8 9]
3×3 Array{Int64,2}:
 1  2  3
 4  5  6
 7  8  9

julia> slice(A, 2)
1-element view(::Array{Int64,2}, :, 2) with eltype Int64:
 4
 5
 6

In this example, the slice function is used with a single index 2. The resulting view is a 3-element array representing the second column of the original array A.

It's important to note that the slice function returns a view of the original array, not a new array. Any modifications made to the view will affect the original array as well.
