findmin(A,dims)

findmin(A, dims) -> (minval, index)

For an array input, returns the value and index of the minimum over the given dimensions.

Examples

1. Find the minimum element and index in an array:

   julia> arr = [8, 2, 5, 1, 9];
   julia> findmin(arr)
   (1, 4)

   This example finds the minimum element in the array arr and returns the value 1 along with its index 4.

2. Find the minimum element and index in a range:

   julia> rng = 1:10;
   julia> findmin(rng)
   (1, 1)

   It finds the minimum element in the range 1:10 and returns the value 1 along with its index 1.

3. Find the minimum element and index in a tuple:

   julia> tpl = (5, 2, 8, 3);
   julia> findmin(tpl)
   (2, 2)

   The function can also be used to find the minimum element and its index in a tuple.

Common mistake example:

julia> findmin([])
ERROR: MethodError: no method matching findmin(::Array{Int64,1})

In this example, an empty array is passed to the findmin function. It results in a MethodError since it expects a non-empty iterable as an argument. Ensure that the input collection is not empty when using findmin.
