ind2sub(a, index)

ind2sub(a, index) -> subscripts

Returns a tuple of subscripts into array a corresponding to the linear index index

Examples

Get subscripts from linear index:
```
julia> dims = (3, 4, 2);
julia> index = 17;
julia> ind2sub(dims, index)
(2, 3, 1)
```
This example returns the subscripts (2, 3, 1) corresponding to the linear index 17 in an array with dimensions (3, 4, 2).
Retrieve subscripts for maximum element:
```
julia> A = [4 2 5; 1 3 6];
julia> index = indmax(A);
julia> i, j = ind2sub(size(A), index);
julia> (i, j)
(2, 3)
```
Here, ind2sub is used to obtain the subscripts (2, 3) for the maximum element in the matrix A.
Multiple subscripts assignment:
```
julia> dims = (2, 2);
julia> index = 3;
julia> i, j = ind2sub(dims, index);
julia> (i, j)
(2, 1)
```
In this example, ind2sub is used to assign the subscripts (2, 1) to variables i and j simultaneously.

It is worth noting that the number of subscripts returned by ind2sub corresponds to the number of dimensions specified in dims.

The format of note supported is markdown, use triple backtick to start and end a code block.
