ndims

ndims(A) -> Integer

Returns the number of dimensions of A

Examples

Get the number of dimensions of an array:
```
julia> arr = [1, 2, 3, 4, 5];
julia> ndims(arr)
1
```
This example returns 1 since arr is a one-dimensional array.
Check the number of dimensions of a matrix:
```
julia> mat = [1 2 3; 4 5 6; 7 8 9];
julia> ndims(mat)
2
```
It returns 2 as mat is a two-dimensional matrix.

Get the number of dimensions of a multi-dimensional array:

julia> cube = [1 2 3; 4 5 6; 7 8 9], [10 11 12; 13 14 15; 16 17 18], [19 20 21; 22 23 24; 25 26 27];
julia> ndims(cube)
3

This example returns 3 as cube is a three-dimensional array.

Common mistake example:

julia> str = "Hello, world!";
julia> ndims(str)
ERROR: MethodError: no method matching ndims(::String)

In this example, ndims is called on a string str. However, ndims is not defined for strings. It's important to note that ndims works for arrays and matrices, not for other data types like strings or integers.
