strides

strides(A)

Returns a tuple of the memory strides in each dimension

Examples

1. Get the memory strides of a 1-dimensional array:

   julia> arr = [1, 2, 3, 4, 5];
   julia> strides(arr)
   (1,)

   In this example, the strides function returns a tuple with a single value (1,). This indicates that the array arr has a stride of 1 in the only dimension.

2. Get the memory strides of a 2-dimensional array:

   julia> matrix = [1 2 3; 4 5 6];
   julia> strides(matrix)
   (3, 1)

   The strides function returns a tuple (3, 1) for the 2-dimensional array matrix. This means that the memory stride in the first dimension is 3 and in the second dimension is 1.

3. Get the memory strides of a multi-dimensional array:

   julia> tensor = [1 2 3; 4 5 6; 7 8 9];
   julia> strides(tensor)
   (3, 1)

   Here, the strides function returns a tuple (3, 1) for the multi-dimensional array tensor. It indicates that the memory stride in the first dimension is 3 and in the second dimension is 1.

Common mistake example:

julia> x = [1 2 3; 4 5 6];
julia> strides(x)
ERROR: MethodError: no method matching strides(::Array{Int64,2})

In this example, the strides function is used on a 2-dimensional array. However, the function does not accept 2-dimensional arrays as input. It is important to provide the correct input type to the strides function to avoid this error.
